A disabled nscd breaks nss module loading on NixOS, and systemd without
its nss modules doesn't really work either - instead of silently
disabling its nss modules if nscd is disabled, let the assertion in
nsswitch handle this.
nixos/modules/config/nsswitch.nix uses `passwdArray` for both `passwd`
and `group`, but when moving this into the systemd module in
c0995d22ee, it didn't get split
appropriately.

The configured mbuffer path will be called on both the source and target
system. If you use pkgs.mbuffer from the source host and the target host
does not have this exact derivation, you will get a broken pipe when
sending snapshots. This is the case when transferring to a non-NixOS
system or to a host with a different mbuffer version.
In /etc/doas.conf, the last-matched rule will override all
previously-matched rules. Thus, make the default rule show up first (but
still allow some wiggle room for a user to `mkBefore` it), before any
user-defined rules.
the options should not be set as we already change user with service
file, man mpd.conf says "Do not use this option if you start MPD as an
unprivileged user"
The group option actually is not documented at all anymore and probably
no longer exists.
These options get in the way of setting up confinement for the service,
as it would otherwise be pretty straightforward to setup, but even if
mpd is not root it would check the user exists within the chroot which
is more work (need to get nss working):
systemd.services.mpd = {
serviceConfig.BindPaths = [
# mpd state dir
"/var/lib/mpd"
# notify systemd service started up
"/run/systemd/notify"
];
serviceConfig.BindReadOnlyPaths = [
"/path/to/music:/var/lib/mpd/music"
];
# ProtectSystem is not compatible with confinement
serviceConfig.ProtectSystem = lib.mkForce false;
confinement = {
enable = true;
binSh = null;
mode = "chroot-only";
};
};
Systemd ProtectSystem is incompatible with the chroot we make
for confinement. The options is redundant with what we do anyway
so warn if it had been set and advise to disable it.

This test is sometimes flaky on hydra as at the time of the `git clone`
the network isn't really configured yet[1]. That problem doesn't seem to
occur locally but if you run it on a machine with high enough load (such
as hydra build machines). Hopefully this will make the test not flaky
anymore.

The test harness provides the commands it wishes to run in Bourne
syntax. This fails if the user uses a different shell. For example,
with fish:
machine.wait_for_unit("graphical-session.target", "alice")
machine # fish: Unsupported use of '='. To run '-u`' with a modified environment, please use 'env XDG_RUNTIME_DIR=/run/user/`id -u`…'
machine # XDG_RUNTIME_DIR=/run/user/`id -u` systemctl --user --no-pager show "graphical-session.target"
machine # ^
machine # [ 16.329957] su[1077]: pam_unix(su:session): session closed for user alice
error: retrieving systemctl info for unit "graphical-session.target" under user "alice" failed with exit code 127
This will make dbus socket activation for it work
When `systemd-resolved` is restarted; this would lead to unavailability
of DNS lookups. You're supposed to use DBUS socket activation to buffer
resolved requests; such that restarts happen without downtime
By default, postgres prefixes each log line with a timestamp. On NixOS
logs are written to journal anyway, so they include an external
timestamp, so the timestamp ends up being printed twice, which clutters
the log.
* Add a module option to change the log prefix.
* Set it to upstream default sans timestamp.
This completes the removal of the nested log feature, which previously
got removed from Nix, Hydra, stdenv and GNU Make. In particular, this
means that the output of VM builds no longer contains a copy of
jQuery.
If a program (e.g. nixos-install) writes more than 1000 lines to
stderr during execute(), then process_serial_output() deadlocks
waiting for the queue to be processed. So use an unbounded queue
instead.
We should probably get rid of the structured log output (log.xml),
since then we don't need the log queue anymore.
'nix build' is an experimental command so we shouldn't use it
yet. (nixos-rebuild also uses 'nix', but only when using flakes, which
are themselves an experimental feature.)
This reverts commits 9d0de0dc57,
27d2857a99. 'nix ping-store' is an
experimental command so it doesn't work in Nix 2.4 unless you set
'experimental-features = nix-command' in nix.conf.
This seems to have worked in 15f105d41f (5
months ago) but broke somewhere in the meantime.
The current module doesn't seem to be underdocumented and might need a
serious refactor. It requires quite some hacks to get it to work (see
https://github.com/NixOS/nixpkgs/issues/86305#issuecomment-621129942),
or how the ldap.nix test used systemd.services.openldap.preStart and
made quite some assumptions on internals.
Mic92 agreed on being added as a maintainer for the module, as he uses
it a lot and can possibly fix eventual breakages. For the most basic
startup breakages, the remaining openldap.nix test might suffice.
`doas` is a lighter alternative to `sudo` that "provide[s] 95% of the
features of `sudo` with a fraction of the codebase" [1]. I prefer it to
`sudo`, so I figured I would add a NixOS module in order for it to be
easier to use. The module is based off of the existing `sudo` module.
