There are security fixes in multiple packages /cc #32117,
so I'm merging a little earlier, with a few thousand jobs
still not finished on Hydra for x86_64-darwin and aarch64-linux.
- /var/run -> /run as the former is deprecated
- configure openal to use pulseaudio if pulseaudio is enabled
- configure libao to use pulseaudio if pulseaudio is enabled
For some reason, the GNOME 3.26 update broke the overrides. It turns
out the overrides now need to come before the overridden schemas in the
XDG_DATA_DIRS variable. This is not possible in general due to applications
prefixing the variable (e.g. in wrapGAppsHook).
To fix this, a new environment variable NIX_GSETTINGS_OVERRIDES_DIR
was introduced. It has greater priority than XDG_DATA_DIRS but lower
than GSETTINGS_SCHEMA_DIR. A separate variable was chosen in order not
to block the built-in one for users.
With libinput used for keyboard, base rules produce incorrect keyboard
layouts. We are removing the option as recommended in the XKB configuration
guide [1] to let X server choose the ruleset. It looks like it chooses
evdev rules which seem to work for some reason

The munin-node service used wrapProgram to inject environment variables.
This doesn't work because munin plugins depend on argv[0], which is
overwritten when the executable is a script with a shebang line (example
below).
This commit removes the wrappers and instead passes the required
environment variables to munin-node.
Eliminating the wrappers resulted in some broken plugins, e.g., meminfo
and hddtemp_smartctl. That was fixed with the per-plugin configuration.
Example:
The plugin if_eth0 is a symlink to /.../plugins/if_, which uses $0
to determine that it should monitor traffic on the eth0 interface.
if_ is a wrapped program, and runs `exec -a "$0" .if_-wrapped`
.if_-wrapped has a "#!/nix/.../bash" line, which results in bash
changing $0, and as a result the plugin thinks my interface
is called "-wrapped".
Changed extraUsers -> users and one case of extraGroups -> groups in nixos manual chapter 7.
According to chatter on IRC these are the proper names for these configuration options nowadays.
Modified based on feedback from Jörg Talheim.
Previously only the line numbers of a giant, internally generated XML file were
printed, without any kind of debuggability.
Now at least the mentioned lines are printed with a little bit of surrounding
context (to have something to grep for).
