Declared by:

boot.loader.grub.copyKernels

Whether the GRUB menu builder should copy kernels and initial ramdisks to /boot. This is done automatically if /boot is on a different partition than /.

Type: boolean

Default: false

Declared by:

boot.loader.grub.default

Index of the default menu item to be booted.

Type: signed integer or string

Default: "0"

Declared by:

boot.loader.grub.device

The device on which the GRUB boot loader will be installed. The special value nodev means that a GRUB boot menu will be generated, but GRUB itself will not actually be installed. To install GRUB on multiple devices, use boot.loader.grub.devices.

Type: string

Default: ""

Example: "/dev/disk/by-id/wwn-0x500001234567890a"

Declared by:

boot.loader.grub.efiInstallAsRemovable

Whether to invoke grub-install with``–removable``.

Unless you turn this on, GRUB will install itself somewhere in``boot.loader.efi.efiSysMountPoint`` (exactly where depends on other config variables). If you’ve set``boot.loader.efi.canTouchEfiVariables`` AND you are currently booted in UEFI mode, then GRUB will use``efibootmgr`` to modify the boot order in the EFI variables of your firmware to include this location. If you are *not* booted in UEFI mode at the time GRUB is being installed, the NVRAM will not be modified, and your system will not find GRUB at boot time. However, GRUB will still return success so you may miss the warning that gets printed (“efibootmgr: EFI variables are not supported on this system.”).

If you turn this feature on, GRUB will install itself in a special location within efiSysMountPoint (namely``EFI/boot/boot$arch.efi``) which the firmwares are hardcoded to try first, regardless of NVRAM EFI variables.

To summarize, turn this on if:

  • You are installing NixOS and want it to boot in UEFI mode, but you are currently booted in legacy mode
  • You want to make a drive that will boot regardless of the NVRAM state of the computer (like a USB “removable” drive)
  • You simply dislike the idea of depending on NVRAM state to make your drive bootable

If set to false, this unit will be a symlink to /dev/null. This is primarily useful to prevent specific template instances (e.g. serial-getty@ttyS0) from being started. Note that enable=true does not make a unit start by default at boot; if you want that, see``wantedBy``.

Type: boolean

Default: true

Declared by:

boot.systemd.targets.<name>.after

If the specified units are started at the same time as this unit, delay this unit until they have started.

Type: list of strings

Default: ``[

Declared by:

boot.systemd.targets.<name>.aliases

Aliases of that unit.

Type: list of strings

Default: ``[

Declared by:

boot.systemd.targets.<name>.before

If the specified units are started at the same time as this unit, delay them until this unit has started.

Type: list of strings

Default: ``[

Declared by:

boot.systemd.targets.<name>.bindsTo

Like ‘requires’, but in addition, if the specified units unexpectedly disappear, this unit will be stopped as well.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.conflicts

If the specified units are started, then this unit is stopped and vice versa.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.description

Description of this unit used in systemd messages and progress indicators.

Type: string

Default: ""

Declared by:

boot.systemd.targets.<name>.documentation

A list of URIs referencing documentation for this unit or its configuration.

Type: list of strings

Default: ``[

Declared by:

boot.systemd.targets.<name>.onFailure

A list of one or more units that are activated when this unit enters the “failed” state.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.partOf

If the specified units are stopped or restarted, then this unit is stopped or restarted as well.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.requiredBy

Units that require (i.e. depend on and need to go down with) this unit. The discussion under wantedBy applies here as well: inverse .requires symlinks are established.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.requires

Start the specified units when this unit is started, and stop this unit when the specified units are stopped or fail.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.requisite

Similar to requires. However if the units listed are not started, they will not be started and the transaction will fail.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.restartTriggers

Type: list of unspecifieds

Default: ``[

Configure unit start rate limiting. Units which are started more than burst times within an interval time interval are not permitted to start any more.

Type: signed integer

Declared by:

boot.systemd.targets.<name>.unitConfig

Each attribute in this set specifies an option in the``[Unit]`` section of the unit. Seesystemd.unit5 for details.

Type: attribute set of systemd options

Default: ``{

}``

Example: { RequiresMountsFor = "/data"; }

Declared by:

boot.systemd.targets.<name>.wantedBy

Units that want (i.e. depend on) this unit. The standard way to make a unit start by default at boot is to set this option to [ "multi-user.target" ]. That’s despite the fact that the systemd.unit(5) manpage says this option goes in the [Install] section that controls the behaviour of systemctl enable. Since such a process is stateful and thus contrary to the design of NixOS, setting this option instead causes the equivalent inverse .wants symlink to be present, establishing the same desired relationship in a stateless way.

Type: list of strings

Default: ``[

]``

Declared by:

boot.systemd.targets.<name>.wants

Start the specified units when this unit is started.

Type: list of strings

Default: ``[

]``

Declared by:

boot.tmpOnTmpfs

Whether to mount a tmpfs on /tmp during boot.

Type: boolean

Default: false

Declared by:

boot.vesa

(Deprecated) This option, if set, activates the VESA 800x600 video mode on boot and disables kernel modesetting. It is equivalent to specifying [ "vga=0x317" "nomodeset" ] in the option. This option is deprecated as of 2020: Xorg now works better with modesetting, and you might want a different VESA vga setting, anyway.

Type: boolean

Default: false

Declared by:

boot.zfs.enableUnstable

Use the unstable zfs package. This might be an option, if the latest kernel is not yet supported by a published release of ZFS. Enabling this option will install a development version of ZFS on Linux. The version will have already passed an extensive test suite, but it is more likely to hit an undiscovered bug compared to running a released version of ZFS on Linux.

Type: boolean

Default: false

Declared by:

boot.zfs.devNodes

Name of directory from which to import ZFS devices.

This should be a path under /dev containing stable names for all devices needed, as import may fail if device nodes are renamed concurrently with a device failing.

Type: path

Default: "/dev/disk/by-id"

Example: "/dev/disk/by-id"

Declared by:

boot.zfs.extraPools

Name or GUID of extra ZFS pools that you wish to import during boot.

Usually this is not necessary. Instead, you should set the mountpoint property of ZFS filesystems to legacy and add the ZFS filesystems to NixOS’s option, which makes NixOS automatically import the associated pool.

However, in some cases (e.g. if you have many filesystems) it may be preferable to exclusively use ZFS commands to manage filesystems. If so, since NixOS/systemd will not be managing those filesystems, you will need to specify the ZFS pool here so that NixOS automatically imports it on every boot.

Type: list of strings

Default: ``[

]``

Example: [ "tank" "data" ]

Declared by:

boot.zfs.forceImportAll

Forcibly import all ZFS pool(s).

This is enabled by default for backwards compatibility purposes, but it is highly recommended to disable this option, as it bypasses some of the safeguards ZFS uses to protect your ZFS pools.

If you set this option to false and NixOS subsequently fails to import your non-root ZFS pool(s), you should manually import each pool with “zpool import -f <pool-name>”, and then reboot. You should only need to do this once.

Type: boolean

Default: true

Declared by:

boot.zfs.forceImportRoot

Forcibly import the ZFS root pool(s) during early boot.

This is enabled by default for backwards compatibility purposes, but it is highly recommended to disable this option, as it bypasses some of the safeguards ZFS uses to protect your ZFS pools.

If you set this option to false and NixOS subsequently fails to boot because it cannot import the root pool, you should boot with the``zfs_force=1`` option as a kernel parameter (e.g. by manually editing the kernel params in grub during boot). You should only need to do this once.

Type: boolean

Default: true

Declared by:

boot.zfs.requestEncryptionCredentials

Request encryption keys or passwords for all encrypted datasets on import. For root pools the encryption key can be supplied via both an interactive prompt (keylocation=prompt) and from a file (keylocation=file://). Note that for data pools the encryption key can be only loaded from a file and not via interactive prompt since the import is processed in a background systemd service.

Type: boolean

Default: true

Declared by:

console.packages

List of additional packages that provide console fonts, keymaps and other resources for virtual consoles use.

Type: list of packages

Default: "with pkgs.kbdKeymaps; [ dvp neo ]"

Declared by:

console.earlySetup

Enable setting virtual console options as early as possible (in initrd).

Type: boolean

Default: false

Declared by:

console.extraTTYs

TTY (virtual console) devices, in addition to the consoles on which mingetty and syslogd run, that must be initialised. Only useful if you have some program that you want to run on some fixed console. For example, the NixOS installation CD opens the manual in a web browser on console 7, so it sets to ["tty7"].

Type: list of strings

Default: ``[

]``

Example: [ "tty8" "tty9" ]

Declared by:

console.font

The font used for the virtual consoles. Leave empty to use whatever the setfont program considers the default font.

Type: string

Default: "Lat2-Terminus16"

containers.<name>.ephemeral

Runs container in ephemeral mode with the empty root filesystem at boot. This way container will be bootstrapped from scratch on each boot and will be cleaned up on shutdown leaving no traces behind. Useful for completely stateless, reproducible containers.

Note that this option might require to do some adjustments to the container configuration, e.g. you might want to set``systemd.network.networks.$interface.dhcpConfig.ClientIdentifier`` to “mac” if you use macvlans option. This way dhcp client identifier will be stable between the container restarts.

Note that the container journal will not be linked to the host if this option is enabled.

Some NixOS packages provide debug symbols. However, these are not included in the system closure by default to save disk space. Enabling this option causes the debug symbols to appear in /run/current-system/sw/lib/debug/.build-id, where tools such as gdb can find them. If you need debug symbols for a package that doesn’t provide them by default, you can enable them as follows:

Declared by:

jobs.<name>.wantedBy

Units that want (i.e. depend on) this unit. The standard way to make a unit start by default at boot is to set this option to [ "multi-user.target" ]. That’s despite the fact that the systemd.unit(5) manpage says this option goes in the [Install] section that controls the behaviour of systemctl enable. Since such a process is stateful and thus contrary to the design of NixOS, setting this option instead causes the equivalent inverse .wants symlink to be present, establishing the same desired relationship in a stateless way.

Turn on proxy_arp for this device (and proxy_ndp for ipv6). This is mainly useful for creating pseudo-bridges between a real interface and a virtual network such as VPN or a virtual machine for interfaces that don’t support real bridging (most wlan interfaces). As ARP proxying acts slightly above the link-layer, below-ip traffic isn’t bridged, so things like DHCP won’t work. The advantage above using NAT lies in the fact that no IP addresses are shared, so all hosts are reachable/routeable.

WARNING: turns on ip-routing, so if you have multiple interfaces, you should think of the consequence and setup firewall rules to limit this.

Type: boolean

Default: true

Declared by:

nix.requireSignedBinaryCaches

If enabled (the default), Nix will only download binaries from binary caches if they are cryptographically signed with any of the keys listed in. If disabled, signatures are neither required nor checked, so it’s strongly recommended that you use only trustworthy caches and https to prevent man-in-the-middle attacks.

Type: boolean

Default: true

Directories from the host filesystem to be included in the sandbox.

Type: list of strings

Default: ``[

]``

Default: [ "root" ]

Example: [ "root" "alice" "@wheel" ]

Declared by:

nix.useSandbox

If set, Nix will perform builds in a sandboxed environment that it will set up automatically for each build. This prevents impurities in builds by disallowing access to dependencies outside of the Nix store by using network and mount namespaces in a chroot environment. This is enabled by default even though it has a possible performance impact due to the initial setup time of a sandbox for each build. It doesn’t affect derivation hashes, so changing this option will not trigger a rebuild of packages.

Type: boolean or one of “relaxed”

Default: true

Declared by:

nixops.enableDeprecatedAutoLuks

Whether to enable Enable the deprecated NixOps AutoLuks module.

Type: boolean

Default: false

Example: true

nixpkgs.config

The configuration of the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to set package configuration options.

Ignored when nixpkgs.pkgs is set.

Type: nixpkgs config

Default: ``{

}``

Example:

{ allowBroken = true; allowUnfree = true; }

Declared by:

nixpkgs.crossSystem

Specifies the platform for which NixOS should be built. Specify this only if it is different fromnixpkgs.localSystem, the platform*on* which NixOS should be built. In other words, specify this to cross-compile NixOS. Otherwise it should be set as null, the default. See its description in the Nixpkgs manual for more details.

Ignored when nixpkgs.pkgs is set.

Type: null or attribute set

Default: (import "${nixos}/../lib").lib.systems.examples.aarch64-multiplatform

Example: { config = "aarch64-unknown-linux-gnu"; system = "aarch64-linux"; }

Declared by:

nixpkgs.localSystem

Specifies the platform on which NixOS should be built. Whennixpkgs.crossSystem is unset, it also specifies the platform for which NixOS should be built. If this option is unset, it defaults to the platform type of the machine where evaluation happens. Specifying this option is useful when doing distributed multi-platform deployment, or when building virtual machines. See its description in the Nixpkgs manual for more details.

Ignored when nixpkgs.pkgs is set.

Type: attribute set

Default: (import "${nixos}/../lib").lib.systems.examples.aarch64-multiplatform

Example: { config = "aarch64-unknown-linux-gnu"; system = "aarch64-linux"; }

Declared by:

nixpkgs.overlays

List of overlays to use with the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to override packages globally. Each function in the list takes as an argument the original Nixpkgs. The first argument should be used for finding dependencies, and the second should be used for overriding recipes.

If nixpkgs.pkgs is set, overlays specified here will be applied after the overlays that were already present in nixpkgs.pkgs.

Type: list of nixpkgs overlays

Default: ``[

]``

Example:

[
  (self: super: {
    openssh = super.openssh.override {
      hpnSupport = true;
      kerberos = self.libkrb5;
    };
  })
]

Declared by:

nixpkgs.pkgs

If set, the pkgs argument to all NixOS modules is the value of this option, extended with nixpkgs.overlays, if that is also set. Either nixpkgs.crossSystem ornixpkgs.localSystem will be used in an assertion to check that the NixOS and Nixpkgs architectures match. Any other options in nixpkgs.*, notably config, will be ignored.

If unset, the pkgs argument to all NixOS modules is determined as shown in the default value for this option.

The default value imports the Nixpkgs source files relative to the location of this NixOS module, because NixOS and Nixpkgs are distributed together for consistency, so the nixos in the default value is in fact a relative path. The config, overlays,localSystem, and crossSystem come from this option’s siblings.

This option can be used by applications like NixOps to increase the performance of evaluation, or to create packages that depend on a container that should be built with the exact same evaluation of Nixpkgs, for example. Applications like this should set their default value using lib.mkDefault, so user-provided configuration can override it without usinglib.

Note that using a distinct version of Nixpkgs with NixOS may be an unexpected source of problems. Use this option with care.

Type: An evaluation of Nixpkgs; the top level attribute set of packages

Default: import "${nixos}/.." { inherit (cfg) config overlays localSystem crossSystem; }

Example:

import <nixpkgs> {}

Declared by:

nixpkgs.system

Specifies the Nix platform type on which NixOS should be built. It is better to specify nixpkgs.localSystem instead.

{
  nixpkgs.system = ..;
}

is the same as

{
  nixpkgs.localSystem.system = ..;
}

See nixpkgs.localSystem for more information.

Ignored when nixpkgs.localSystem is set. Ignored when nixpkgs.pkgs is set.

Type: string

power.ups.enable

Enables support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units and Solar Controllers.

Type: boolean

Default: false

Declared by:

power.ups.maxStartDelay

This can be set as a global variable above your first UPS definition and it can also be set in a UPS section. This value controls how long upsdrvctl will wait for the driver to finish starting. This keeps your system from getting stuck due to a broken driver or UPS.

Type: signed integer

Default: 45

Declared by:

power.ups.mode

The MODE determines which part of the NUT is to be started, and which configuration files must be modified.

The values of MODE can be:

  • none: NUT is not configured, or use the Integrated Power

Management, or use some external system to startup NUT components. So nothing is to be started.

  • standalone: This mode address a local only configuration, with 1

UPS protecting the local system. This implies to start the 3 NUT layers (driver, upsd and upsmon) and the matching configuration files. This mode can also address UPS redundancy.

  • netserver: same as for the standalone configuration, but also

need some more ACLs and possibly a specific LISTEN directive in upsd.conf. Since this MODE is opened to the network, a special care should be applied to security concerns.

  • netclient: this mode only requires upsmon.

Declared by:

security.allowSimultaneousMultithreading

Whether to allow SMT/hyperthreading. Disabling SMT means that only physical CPU cores will be usable at runtime, potentially at significant performance cost.

The primary motivation for disabling SMT is to mitigate the risk of leaking data between threads running on the same CPU core (due to e.g., shared caches). This attack vector is unproven.

Disabling SMT is a supplement to the L1 data cache flushing mitigation (see security.virtualisation.flushL1DataCache) versus malicious VM guests (SMT could “bring back” previously flushed data).

Type: boolean

Default: true

Declared by:

security.allowUserNamespaces

Whether to allow creation of user namespaces.

The motivation for disabling user namespaces is the potential presence of code paths where the kernel’s permission checking logic fails to account for namespacing, instead permitting a namespaced process to act outside the namespace with the same privileges as it would have inside it. This is particularly damaging in the common case of running as root within the namespace.

When user namespace creation is disallowed, attempting to create a user namespace fails with “no space left on device” (ENOSPC). root may re-enable user namespace creation at runtime.

Type: integer of at least 16 bits

Default: 2048

Declared by:

security.dhparams.params

Diffie-Hellman parameters to generate.

The value is the size (in bits) of the DH params to generate. The generated DH params path can be found in``config.security.dhparams.params.*name*.path``.

Note

The name of the DH params is taken as being the name of the service it serves and the params will be generated before the said service is started.

Warning

If you are removing all dhparams from this list, you have to leave for at least one activation in order to have them be cleaned up. This also means if you rollback to a version without any dhparams the existing ones won’t be cleaned up. Of course this only applies if is``true``.

Note

It’s recommended to not set a specific bit size here, so that users can easily override this by setting.

Type: attribute set of submodule or signed integer convertible to its

Note

If this is false the resulting store path will be non-deterministic and will be rebuilt every time theopenssl package changes.

Type: boolean

Default: true

Type: one of “safe”, “secure”

Default: "safe"

Declared by:

security.duosec.fallbackLocalIP

Duo Unix reports the IP address of the authorizing user, for the purposes of authorization and whitelisting. If Duo Unix cannot detect the IP address of the client, setting``fallbackLocalIP = yes`` will cause Duo Unix to send the IP address of the server it is running on.

If you are using IP whitelisting, enabling this option could cause unauthorized logins if the local IP is listed in the whitelist.

Type: boolean

Default: false

Whether the hypervisor should flush the L1 data cache before entering guests. See also security.allowSimultaneousMultithreading.

null

uses the kernel default

"never"

disables L1 data cache flushing entirely. May be appropriate if all guests are trusted.

"cond"

flushes L1 data cache only for pre-determined code paths. May leak information about the host address space layout.

"always"

flushes L1 data cache every time the hypervisor enters the guest. May incur significant performance cost.

Declared by:

security.wrappers

This option allows the ownership and permissions on the setuid wrappers for specific programs to be overridden from the default (setuid root, but not setgid root).

Note

The sub-attribute source is mandatory, it must be the absolute path to the program to be wrapped.

The sub-attribute program is optional and can give the wrapper program a new name. The default name is the same as the attribute name itself.

Additionally, this option can set capabilities on a wrapper program that propagates those capabilities down to the wrapped, real program.

NOTE: cap_setpcap, which is required for the wrapper program to be able to raise caps into the Ambient set is NOT raised to the Ambient set so that the real program cannot modify its own capabilities!! This may be too restrictive for cases in which the real program needs cap_setpcap but it at least leans on the side security paranoid vs. too relaxed.

Type: attribute set

Default: ``{

}``

Example:

{ sendmail.source = "/nix/store/.../bin/sendmail";
  ping = {
    source  = "${pkgs.iputils.out}/bin/ping";

Declared by:

services.bacula-sd.enable

Whether to enable Bacula Storage Daemon.

Type: boolean

Default: false

Declared by:

services.bacula-sd.autochanger

This option defines Autochanger resources in Bacula Storage Daemon.

Type: attribute set of submodules

Default: ``{

}``

Declared by:

services.bacula-sd.autochanger.<name>.changerCommand

The name-string specifies an external program to be called that will automatically change volumes as required by Bacula. Normally, this directive will be specified only in the AutoChanger resource, which is then used for all devices. However, you may also specify the different Changer Command in each Device resource. Most frequently, you will specify the Bacula supplied mtx-changer script as follows:

"/path/mtx-changer %c %o %S %a %d"

and you will install the mtx on your system (found in the depkgs release). An example of this command is in the default bacula-sd.conf file. For more details on the substitution characters that may be specified to configure your autochanger please see the AutochangersAutochangersChapter chapter of this manual. For FreeBSD users, you might want to see one of the several chio scripts in examples/autochangers.

Type: unspecified

Default: "/etc/bacula/mtx-changer %c %o %S %a %d"

Declared by:

services.bacula-sd.autochanger.<name>.changerDevice

The specified name-string must be the generic SCSI device name of the autochanger that corresponds to the normal read/write Archive Device specified in the Device resource. This generic SCSI device name should be specified if you have an autochanger or if you have a standard tape drive and want to use the Alert Command (see below). For example, on Linux systems, for an Archive Device name of``/dev/nst0``, you would specify``/dev/sg0`` for the Changer Device name. Depending on your exact configuration, and the number of autochangers or the type of autochanger, what you specify here can vary. This directive is optional. See the Using AutochangersAutochangersChapter chapter of this manual for more details of using this and the following autochanger directives.

Type: unspecified

Declared by:

services.bacula-sd.autochanger.<name>.devices

services.bacula-sd.autochanger.<name>.extraAutochangerConfig

Extra configuration to be passed in Autochanger directive.

Type: unspecified

Default: ""

Example:

''

''

Declared by:

services.bacula-sd.device

This option defines Device resources in Bacula Storage Daemon.

Type: attribute set of submodules

Default: ``{

}``

Declared by:

services.bacula-sd.device.<name>.archiveDevice

The specified name-string gives the system file name of the storage device managed by this storage daemon. This will usually be the device file name of a removable storage device (tape drive), for example /dev/nst0 or``/dev/rmt/0mbn``. For a DVD-writer, it will be for example /dev/hdc. It may also be a directory name if you are archiving to disk storage. In this case, you must supply the full absolute path to the directory. When specifying a tape device, it is preferable that the “non-rewind” variant of the device file name be given.

Type: unspecified

Declared by:

services.bacula-sd.device.<name>.extraDeviceConfig

Extra configuration to be passed in Device directive.

Type: unspecified

Default: ""

Example:

''
LabelMedia = yes
Random Access = no
AutomaticMount = no
RemovableMedia = no
MaximumOpenWait = 60
AlwaysOpen = no
''

Declared by:

services.bacula-sd.device.<name>.mediaType

The specified name-string names the type of media supported by this device, for example, DLT7000. Media type names are arbitrary in that you set them to anything you want, but they must be known to the volume database to keep track of which storage daemons can read which volumes. In general, each different storage type should have a unique Media Type associated with it. The same name-string must appear in the appropriate Storage resource definition in the Director’s configuration file.

Even though the names you assign are arbitrary (i.e. you choose the name you want), you should take care in specifying them because the Media Type is used to determine which storage device Bacula will select during restore. Thus you should probably use the same Media Type specification for all drives where the Media can be freely interchanged. This is not generally an issue if you have a single Storage daemon, but it is with multiple Storage daemons, especially if they have incompatible media.

For example, if you specify a Media Type of DDS-4 then during the restore, Bacula will be able to choose any Storage Daemon that handles DDS-4. If you have an autochanger, you might want to name the Media Type in a way that is unique to the autochanger, unless you wish to possibly use the Volumes in other drives. You should also ensure to have unique Media Type names if the Media is not compatible between drives. This specification is required for all devices.

In addition, if you are using disk storage, each Device resource will generally have a different mount point or directory. In order for Bacula to select the correct Device resource, each one must have a unique Media Type.

Type: unspecified

Declared by:

services.bacula-sd.director

This option defines Director resources in Bacula Storage Daemon.

Type: attribute set of submodules

Default: ``{

}``

Declared by:

services.bacula-sd.director.<name>.monitor

If Monitor is set to no, this director will have full access to this Storage daemon. If Monitor is set to``yes``, this director will only be able to fetch the current status of this Storage daemon.

Please note that if this director is being used by a Monitor, we highly recommend to set this directive to yes to avoid serious security problems.

Type: unspecified

Default: "no"

Example: "yes"

Declared by:

services.bacula-sd.director.<name>.password

Specifies the password that must be supplied for the default Bacula Console to be authorized. The same password must appear in the Director resource of the Console configuration file. For added security, the password is never passed across the network but instead a challenge response hash code created with the password. This directive is required. If you have either /dev/random or bc on your machine, Bacula will generate a random password during the configuration process, otherwise it will be left blank and you must manually supply it.

The password is plain text. It is not generated through any special process but as noted above, it is better to use random text for security reasons.

A larger ratio of index size to storage size means smaller blocks of duplicate content are recognized.

If you have 1TB of data, a 4GB hash table (which is to say, a value of 4096) will permit 4KB extents (the smallest possible size) to be recognized, whereas a value of 1024 – creating a 1GB hash table – will recognize only aligned duplicate blocks of 16KB.

Type: signed integer

Default: 1024

Declared by:

services.beesd.filesystems.<name>.spec

Description of how to identify the filesystem to be duplicated by this instance of bees. Note that deduplication crosses subvolumes; one must not configure multiple instances for subvolumes of the same filesystem (or block devices which are part of the same filesystem), but only for completely independent btrfs filesystems.

This must be in a format usable by findmnt; that could be a key=value pair, or a bare path to a mount point.

services.bitwarden_rs.config

The configuration of bitwarden_rs is done through environment variables, therefore the names are converted from camel case (e.g. disable2FARemember) to upper case snake case (e.g. DISABLE_2FA_REMEMBER). In this conversion digits (0-9) are handled just like upper case characters, so foo2 would be converted to FOO_2. Names already in this format remain unchanged, so FOO2 remains FOO2 if passed as such, even though foo2 would have been converted to FOO_2. This allows working around any potential future conflicting naming conventions.

Based on the attributes passed to this config option an environment file will be generated that is passed to bitwarden_rs’s systemd service.

The available configuration options can be found in`the environment template file <https://github.com/dani-garcia/bitwarden_rs/blob/1.13.1/.env.template>`_.

Leaving it blank leaves it up to InetAddress.getLocalHost(). This will always do the Right Thing _if_ the node is properly configured (hostname, name resolution, etc), and the Right Thing is to use the address associated with the hostname (it might not be).

Setting listen_address to 0.0.0.0 is always wrong.

Type: null or string

Relay address (the local IP address that will be used to relay the packets to the peer). Multiple relay addresses may be used. The same IP(s) can be used as both listening IP(s) and relay IP(s).

If no relay IP(s) specified, then the turnserver will apply the default policy: it will decide itself which relay addresses to be used, and it will always be using the client socket IP address as the relay IP address of the TURN session (if the requested relay address family is the same as the family of the client socket).

Type: list of strings

Default: ``[

‘Static’ authentication secret value (a string) for TURN REST API only. If not set, then the turn server will try to use the ‘dynamic’ value in turn_secret table in user database (if present). The database-stored value can be changed on-the-fly by a separate program, so this is why that other mode is ‘dynamic’.

Type: null or string

Default: null

Declared by:

services.coturn.tls-listening-port

TURN listener port for TLS. Note: actually, “plain” TCP and UDP sessions can connect to the TLS and DTLS port(s), too - if allowed by configuration. The TURN server “automatically” recognizes the type of traffic. Actually, two listening endpoints (the “plain” one and the “tls” one) are equivalent in terms of functionality; but we keep both endpoints to satisfy the RFC 5766 specs. For secure TCP connections, we currently support SSL version 3 and TLS version 1.0, 1.1 and 1.2. For secure UDP connections, we support DTLS version 1.

Type: signed integer

Default: 5349

Declared by:

services.coturn.use-auth-secret

TURN REST API flag. Flag that sets a special authorization option that is based upon authentication secret. This feature can be used with the long-term authentication mechanism, only. This feature purpose is to support “TURN Server REST API”, see “TURN REST API” link in the project’s page https://github.com/coturn/coturn/

This option is used with timestamp:

usercombo -> “timestamp:userid” turn user -> usercombo turn password -> base64(hmac(secret key, usercombo))

This allows TURN credentials to be accounted for a specific user id. If you don’t have a suitable id, the timestamp alone can be used. This option is just turning on secret-based authentication. The actual value of the secret is defined either by option static-auth-secret, or can be found in the turn_secret table in the database.

The result is placed to Nix store, and the ~/.gitolite.rc file becomes a symlink to it.

If you already have a customized (or otherwise changed)``~/.gitolite.rc`` file, NixOS will refuse to replace it with a symlink, and the `gitolite-init` initialization service will fail. In this situation, in order to use this option, you will need to take any customizations you may have in``~/.gitolite.rc``, convert them to appropriate Perl statements, add them to this option, and remove the file.

Declared by:

services.journalwatch.filterBlocks

filterBlocks can be defined to blacklist journal messages which are not errors. Each block matches on a log entry field, and the filters in that block then are matched against all messages with a matching log entry field.

All messages whose PRIORITY is at least 6 (INFO) are processed by journalwatch. If you don’t specify any filterBlocks, PRIORITY is reduced to 5 (NOTICE) by default.

All regular expressions are extended Python regular expressions, for details see: http://doc.pyschools.com/html/regex.html

Type: list of submodules

Default: ``[

{ filters = “(Stopped|Stopping|Starting|Started) .*\n(Created slice|Removed slice) user-\d*\.slice\.\nReceived SIGRTMIN\+24 from PID .*\n(Reached target|Stopped target) .*\nStartup finished in \d*ms\.\n”; match = “SYSLOG_IDENTIFIER = systemd”; }

]``

Example: ``[

{ filters = “New session [a-z]?\d+ of user \w+\.\nRemoved session [a-z]?\d+\.\n”; match = “_SYSTEMD_UNIT = systemd-logind.service”; }

{ filters = “pam_unix\(crond:session\): session (opened|closed) for user \w+\n\(\w+\) CMD .*\n”; match = “SYSLOG_IDENTIFIER = /(CROND|crond)/”; }

]``

Each filter is an extended Python regular expression. You can specify multiple filters and separate them by newlines. Lines starting with ‘#’ are comments. Inline-comments are not permitted.

Type: string

Example:

''
(Stopped|Stopping|Starting|Started) .*
(Reached target|Stopped target) .*
''

Declared by:

services.journalwatch.filterBlocks.*.match

Syntax: field = value Specifies the log entry field this block should apply to. If the field of a message matches this value, this patternBlock’s are applied.

Declared by:

services.nghttpx.backends.*.params.affinity

If “ip” is given, client IP based session affinity is enabled. If “none” is given, session affinity is disabled.

Session affinity is enabled (by nghttpx) per-backend pattern. If at least one backend has a non-“none” affinity, then session affinity is enabled for all backend servers sharing the same pattern.

It is advised to set affinity on all backends explicitly if session affinity is desired. The session affinity may break if one of the backend gets unreachable, or backend settings are reloaded or replaced by API.

Please see https://nghttp2.org/documentation/nghttpx.1.html#cmdoption-nghttpx-b for more detail.

Type: one of “ip”, “none”

Default: "none"

Declared by:
