The `--apis=` command line parameter passed to Jitsi Videobridge is
required to monitor a Jitsi Meet instance for example via the prometheus
exporter [jitsiexporter](https://git.xsfx.dev/prometheus/jitsiexporter).

While I personally don't like that we can't easily use
pushDownProperties from the module system and need to rely on internals,
we *already* use internals for the mkOverride case, so adding another
case for mkIf doesn't add a hard-to-find indirection.
I'm merging this, since this fixes a valid use case and it shouldn't
make refactoring worse than before.
The NixOS 21.03 release has been delayed to 21.05. See NixOS/rfcs#80.
There are two instances of 21.03 which have been left as is, since they
are in stateVersion comparisons. This will ensure that existing user
configurations which refer to 21.03 will continue to work.
`unitOption` is only used inside of `attrsOf` wich is perfectly capable of
handling the attrsets from `mkIf`, though the checkUnitConfig test
forbids it. This commit weakens that restriction to allow the usage of
`mkIf` inside of `systemd.services.<name>.serviceConfig.<something>`
etc.
Account for the fact that, when creating a lua package without the
"withPackages" helper, we dont get an extra "lua" attribute in the
package.
Therefore we need to distinguish between the "withPackages" case and the
direct ( or "empty" ) lua package.
For example with this nixos config:
```nix
{
services.httpd = {
enable = true;
package = pkgs.apacheHttpd.override {
luaSupport = true;
lua5 = pkgs.lua5_3.withPackages (ps: with ps; [ luafilesystem ] );
};
};
}
```
Here we say that we want to have apache to use a lua, packaged with the
`luafilesystem` module so that we can `require` that in scripts to
render http responses. There, the set that gets assigned to `lua5 ` does
not have a `luaversion` attribute, rather it has a `lua` attribute
wherein lies a `luaversion` attribute. If we dont package additional
modules, then we dont have that `lua` attribute in between and rather
directly have to use `luaversion` directly.
For sa-update we care about two successful codes:
* 1 -> no updates available: exit successfully
* 0 -> updates have been installed: run sa-compile and pass
through its return code
sa-compile speeds up processing the rules by compiling them from Perl to
C. This needs to be run after every update and is saved in the local
state directory by Perl and SpamAssassin version.
Let systemd create SpamAssassin's state directory and populate it using the
regular updater service. Depend on the updater service on boot but do not
propagate failure to the main service.
spamd's commands to start and reload the service are still executed as
root but user/group are set to properly chown the state directory to the
target user. spamd drops privileges itself for its runner children but
preserves root on the main daemon (to listen and re-exec).
sa-update currently runs as part of the pre-start script of spamd. The
network is not guaranteed to be online at that point and even if we
were to depend on that, it makes the bootup brittle, as there is a
reliance on SpamAssassin's update server as a startup dependency on
boot.
Refactor the setup to move the pre-start script into its own unit.
This allows to perform the setup task only once. Continuous updates
are already done by sa-update.service triggered by sa-update.timer.
Only run sa-update in case /var/lib/spamassassin is empty.
While we are on it, let sa-update.service depend on the network being
online.
