A default of 0 means that if you deploy two NixOS boxes with the default
configuration, the second will fail because the brokerId was already in
use. Using -1 instead tells it to pick one automatically at first start.
This provides a default console_cmd for the slim display-manager.
When the user enters "console" as the user name, slim will run this
command.
Having a default is rather important; the virtual terminals don't work
with some display drivers, so having a broken X session can leave you
locked out of your machine.
Without it, the following error is shown in the "Add Printer" window:
Failed to group devices: 'The name org.fedoraproject.Config.Printing was not provided by any .service files'
* Fix the FW names
FW_REFUSE was removed and nixos-fw-input was renamed to nixos-fw.
* Update the comment (documentation) at the top
Order the chains of the main table alphabetically (like in the rest of
the file) and add nixos-fw-rpfilter (from the raw table) and nixos-drop
(used while reloading the firewall).
* Refactor the module (mainly comments)
- Move some attributes to the top for better visibility (that should
hopefully make it easier to read and understand this module without
jumping around too much).
- Add some missing examples and improve some descriptions.
- Reorder the mkOption attributes for consistency.
- Wrap lines at 72 characters.
- Use two spaces between sentences.
This patch add a new argument to Nixpkgs default expression named "overlays".
By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`,
or from the directory `~/.nixpkgs/overlays/`. If the environment variable does not name a valid directory
then this mechanism would fallback on the home directory. If the home directory does not exists it will
fallback on an empty list of overlays.
The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the
content of Nixpkgs, with additional set of packages. The overlays, i-e directory, files, symbolic links
are used in alphabetical order.
The simplest overlay which extends Nixpkgs with nothing looks like:
```nix
self: super: {
}
```
More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query
the final result of the fix-point.
An example of overlay which extends Nixpkgs with a small set of packages can be found at:
https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix
To use this file, checkout the repository and add a symbolic link to
the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.
This adds pulseaudio.daemon.config, which is a set of keys to values
which are directly translated to keys and values of pulseaudio's
daemon.conf, e. g.
hardware.pulseaudio.daemon.config = { flat-volumes = "no"; }
becomes
flat-volumes=no
in pulse/daemon.conf.
The reason being less mental overhead when reading upstream
documentation. Examples can be pasted right into the configuration
instead of translating to Nix attrset first.
Make sure that the output of the sieve compiler produces files that
have a newer time stamp than the source sieve script. Otherwise you
get errors in the logs about Dovecot not being able to compile do to a
permission issue.
ckb is a driver for Corsair keyboards/mice. It also contains a graphical tool for configuring their LED backlight settings.
The driver is implemented as a userland daemon. A NixOS module is included that runs this as a systemd service.
The content of programs.zsh.interactiveShellInit was
inserted too soon in the generated zshrc
This caused some settings related to autocompletion to be ignored
This reverts commit 712e62c260.
This commit broke NixOS containers. Systemd wouldn't detect if a container
started successfully and would kill it again after a grace period.
Additionally this prints mount errors due to already mounted filesystems
at boot.
I have left in 2 NixOS custom config directives, so the configuration
should be the same with the only change in behaviour being that the
service is not eagerly loaded but in fact only socket activated, which
it should be.
Using outputsToInstall the intended behaviour of including host and dnsutils
when bind is installed can be implemented instead of using symlinks to fix
installing all outputs individually with nix-env.
Fixes#19761.
It hides bugs and do you ever actually want to serve up an empty directory?
It was pretty confusing to me when it tried to write into a read-only store
path because I accidentally pointed it to the wrong store path.
Until now nixos only delivered the latest zfs release. This release is often not
compatible with the latest mainline kernel. Therefor an unstable variant is
added, which might be based on testing releases or git revisions.
fixes#21359
`configuration` seems to be a reference to an argument that was
removed seven years ago in commit 2892aed7.
`configuration.nix` makes it a big more clear what we're referring to.

This code in amazon-image.nix:
if mountFS "$device" "$mp" "" auto; then
if [ -z "$diskForUnionfs" ]; then diskForUnionfs="$mp"; fi
fi
relies on mountFS to return a zero exit status if mounting
succeeds. But the lustrateRoot check in mountFS was causing a non-zero
exit status. As a result /disk0 would be mounted, but not used for
/tmp.
(cherry picked from commit d082ed8c35dec48aee2afd1303b3c8b2a1b242b0)
/etc/hostname is the file used by hostnamectl(1) and the
org.freedesktop.hostname1 dbus service (both provided by systemd) to get
the "static hostname". Better provide it so that users of those
tools/services get a proper hostname.
An example of an issue created by the lack of /etc/hostname is that the
bluetooth stack on NixOS identifies itself to peers as "BlueZ $VERSION"
instead of the hostname.

Changes v1 -> v2:
* ensure /etc/hostname ends with a newline
* cpu-freq: Try powersave if ondemand is not available
* Revert "cpu-freq: Try powersave if ondemand is not available"
This reverts commit 4dc56db37e32dcfecd667ebbf88263e47b296097.
Consult available scaling governors; for freshly generated configs, this provides a better experience than relying on a default that might not work everywhere.
