Commit 7addb1c0ec disabled this as a
side effect of switching gnome-terminal to gnome-console, but it’s
still useful for gnome-console.

Lo and behold, we're finally catching up with Mozillas very own firefox
build in terms of speed.
PGO is an optimization technique in which in a first step we create a
build that supports instrumentation, meaning we can use it to create a
profile of how the browser behaved during usage. Then in a second pass
we create the final build that uses the acquired profiling data to
optimize the browser for the workload it actually received during
profiling.
The downside is that with PGO we now need to build Firefox twice, which
increases the build time from around 20 minutes to roughly 50 minutes.
In the Speedometer 2.0 benchmark multiple tests could see a
responsiveness improvemeant around 20-25%, which makes the increased
build time well worth it.
Sadly this benefit seems limited to x86_64-linux, builds on
aarch64-linux get stuck during profiling and I haven't found out why.
Finally, after a long time, we can say:
Closes: #76484
Supersedes: #129503
We can perform most of the mkdir/ln/rm using systemd-tmpfiles
instead which cleans up the script.
/bin and /home are created by their activation script snippets
usbfs is deprecated and unused.
hwclock seems to be automatically executed by systemd on startup.
The mkswap to prevent hibernation cycles seems to be executed by systemd
as well since the provided regression tests succeeds.
Before this patch, services.dendrite.environmentFile is used for
secrets and environment variable substitution only happens when this
option is used.
systemd-247 provides a mechanism called LoadCredential for secrets and
it is better than environment file. See the section of Environment=
in the manual of systemd.exec for more information.
This patch always substitute environment variables, which enables the
usage of systemd LoadCredential.
* With the upgrade to waydroid to 1.2.0, dependencies that previously
were shipped in the service's path have been moved to the waydroid
package.
* Make sure /var/lib/misc exists when starting waydroid. As required
by dnsmasq
This patch allows creation of files like
/etc/systemd/system/user-.slice.d/limits.conf with
systemd.units."user-.slice.d/limits.conf" = {
text = ''
[Slice]
CPUAccounting=yes
CPUQuota=50%
'';
};
which previously threw an error
Also renames the systemd-unit-path test to sytsemd-misc, and extends it to
test that `systemd.units` can handle directories. In this case we make
sure that resource limits specified in user slices apply.
While doing kernel development with the nixos testing infrastructure, it
is useful to quickly compile the kernel on the side and boot it in the testing VM.
This patch allows overriding the kernel through the environment
variable. For example, the following:
$ NIXPKGS_QEMU_KERNEL_testvm=$LINUX_SRC/arch/x86/boot/bzImage $VM/bin/nixos-test-driver
runs testvm testing VM with the fresh kernel compiled in $LINUX_SRC.

GNOME Shell 42 switched an icon for the accessibility menu in the top panel
to one from gnome-control-center instead of a legacy one from adwaita-icon-theme:
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2155
Let’s add that dependency to the systemd unit since installing it
through `environment.systemPackages` is not enough due to environment isolation.
The tests complained:
/nix/store/nm3nf5y4hzgmy00lw5s6ls68j38y84y0-gjs-1.72.0-installedTests/libexec/installed-tests/gjs/scripts/testCommandLineModules.sh: line 90: gjs-console: command not found
But they still passed.
Sendto device selection is removed in gnome-bluetooth 42.
I decide it is not worth to maintain a legacy gnome-bluetooth
package for the contract.
This should also be broken in elementary OS 7.
The current wrapper only includes vim, gvim and the man pages
(optionally). This rewrite distinguishes two scenarios, which I expect
cover the majority of use cases:
- standalone mode, when `name != "vim"`, means the user already has a
vim in scope and only wants to add a customized version with a
different name. In this case we only include wrappers for `/bin/*vim`.
- non-standalone mode, when `name == "vim"`, means the user expects a
normal vim package that uses the specified configuration. In this case
we include everything in the original derivation, with wrappers for
all the executables that accept a vimrc.
Browser Integration requires setgid and setuid programs, which needs to be done in the system configuration.
This is cleaner than the ad-hoc ways we have to set things up for platforms without a global configuration file.
* nixos/earlyoom: bring the module up to date
Removes deprecated option `ignoreOOMScoreAdjust`, introduces `killHook`
as a replacement for `notificationsCommand`, and adds an `extraArgs`
option for things not covered by the module.
* nixos/earlyoom: add nixos test
* nixos/earlyoom: add reportInterval
Allows setting the interval for logging a memory report. Defaults to
3600 following upstream
(https://github.com/rfjakob/earlyoom/blob/master/earlyoom.default#L5)
to avoid flooding logs.
* nixos/earlyoom: add free{Mem,Swap}KillThreshold
Fixes https://github.com/NixOS/nixpkgs/issues/83504
When a NixOS system uses flakes, i.e., /etc/nixos/flake.nix exists, it
is impossible to use nixos-rebuild to build a pre-flake
configuration.nix. Of course, one can directly use nix command to
build the configuration, but not everybody remembers the correct nix
options to do that.
With the new option, it is possible to build a pre-flake configuration
with command like this:
nixos-rebuild build-vm -I nixos-config=./vm.nix --no-flake
The option might be useful for people following older pre-flake
tutorials on a flake-based system.
In https://github.com/NixOS/nixpkgs/pull/142747, the implementation
behind Machine.execute() has been changed to pipe all the command's
output into base64 on the guest machine.
Unfortunately this means that base64 is blocking until stdout is closed,
which in turn means that we now need to make sure that whenever we run a
program in background via "&" we also need to make sure to close stdout,
which we do by redirecting stdout to stderr.

This adds the option `networking.wg-quick.interfaces.<name>.autostart`, which defaults to `true`, which is the previous behavior. With this option set to `false`, the systemd-unit will no longer be set to `wantedBy = [ "multi-user.target" ]` and therefore the tunnel has to be enabled/disabled via `systemctl start/stop wg-quick-<name>`.

Naively deduplicate VLANs in the python driver for NixOS tests. The
current implementation accidentally works, since the VLan class mutates
the environment. On construction it sets QEMU_VDE_SOCKET_${id} and this
environment variable gets overwritten once a second VLAN with the same
id is constructed. Because the NIC flags passed to qemu just use the
QEMU_VDE_SOCKET_${id} environment variable, this implicitly chooses a
single vde_switch process for each VLAN.
However, this leads to unusable vde_switch processes being spawned in
each test run and as a side effect makes it impossible to access the
correct VLan objects in the interactive test driver. It also makes it
remarkably hard to understand why the current implementation ever
worked.
The Nix-provided `nix-daemon.socket` file has a
> ConditionPathIsReadWrite=/nix/var/nix/daemon-socket/socket
line, to skip that unit if /nix/var/nix/daemon-socket/socket is
read-only (which is the case in some nixos-containers with that folder
bind-ro-mounted from the host).
In these cases, the unit was skipped.
Systemd 250 (rightfully) started to also skip in these cases:
> [ 237.187747] systemd[1]: Nix Daemon Socket was skipped because of a failed condition check (ConditionPathIsReadWrite=/nix/var/nix/daemon-socket).
However, systemd < 250 didn't skip if /nix/var/nix/daemon-socket/socket
didn't /exist at all/, and we were relying on this bug in the case for
fresh NixOS systems, to have /nix/var/nix/daemon-socket/socket created
initially.
Move the creation of that folder to systemd-tmpfiles, by shipping an
appropriate file in `${nixPackage}/lib/tmpfiles.d/nix-daemon.conf`
(NixOS/nix#6285).
In the meantime, set a systemd tmpfiles rule manually in NixOS.
This has been tested to still work with read-only bind-mounted
/nix/var/nix/daemon-socket/socket in containers, it'll keep them
read-only ;-)
some change in the last 24 hours altered the behaviour of st such that
it now dies with a non-zero exit code when the shell exits, so kill is
now necessary
For now at least. I expect someone will find a working type later.
It's incorrect and was causing bad issues. Example test case:
nix-instantiate nixos/release.nix -A tests.xfce.x86_64-linux --dry-run
This is a partial revert of commit b2d803c from PR #162271.
* _7zz: correct license and remove p7zip dependency
The code under Compress/Rar* is licensed under a specific unRAR license
Also Compress/LzfseDecoder.cpp is covered by BSD3
The unRAR code is removed from the `.tar.xz` since the license posits you
agree or remove the code from your hard drive
This adds some complexity to updating 7zz so there is also an update
script
Meta has been updated and tweaked
Source is now downloaded from sourceforge in the `.tar.xz` version to
avoid depending on p7zip
* _7zz: add notice of the license updates and optional unRAR licenced code
Currently it is only possible to add upstream _system_ units. The option
systemd.additionalUpstreamSystemUnits can be used for this.
However, this was not yet possible for systemd.user. In a similar
fashion this was added to systemd-user.nix.
This is intended to have other modules add upstream units.
