Instead of setting User/Group only when DynamicUser is disabled, the
previous version of the code set it only when it was enabled. This
caused services with DynamicUser enabled to actually run as nobody, and
services without DynamicUser enabled to run as root.
Regression from fbb7e0c82f.
This cleans up the CockroachDB expression, with a few suggestions from
@aszlig.
However, it brought up the note of using systemd's StateDirectory=
directive, which is a nice feature for managing long-term data files,
especially for UID/GID assigned services. However, it can only manage
directories under /var/lib (for global services), so it has to introduce
a special path to make use of it at all in the case someone wants a path
at a different root.
While the dataDir directive at the NixOS level is _occasionally_ useful,
I've gone ahead and removed it for now, as this expression is so new,
and it makes the expression cleaner, while other kinks can be worked out
and people can test drive it.
CockroachDB's dataDir directive, instead, has been replaced with
systemd's StateDirectory management to place the data under
/var/lib/cockroachdb for all uses.
There's an included RequiresMountsFor= clause like usual though, so if
people want dependencies for any kind of mounted device at boot
time/before database startup, it's easy to specify using their own
mount/filesystems clause.
This can also be reverted if necessary, but, we can see if anyone ever
actually wants that later on before doing it -- it's a backwards
compatible change, anyway.

Currently there are two calls to curl in the reloadScript, neither which
check for errors. If something is misconfigured (like wrong authToken),
the only trace that something wrong happened is this log message:
Asking Jenkins to reload config
<h1>Bad Message 400</h1><pre>reason: Illegal character VCHAR='<'</pre>
The service isn't marked as failed, so it's easy to miss.
Fix it by passing --fail to curl.
While at it:
* Add $curl_opts and $jenkins_url variables to keep the curl command
lines DRY.
* Add --show-error to curl to show short error message explanation when
things go wrong (like HTTP 401 error).
* Lower-case the $CRUMB variable as upper case is for exported environment
variables.
The new behaviour, when having wrong accessToken:
Asking Jenkins to reload config
curl: (22) The requested URL returned error: 401
And the service is clearly marked as failed in `systemctl --failed`.
This also includes a full end-to-end CockroachDB clustering test to
ensure everything basically works. However, this test is not currently
enabled by default, though it can be run manually. See the included
comments in the test for more information.
Closes #51306. Closes #38665.

As the comment notes, restarts/exits of dhcpcd generally require
restarting the NTP service since, if name resolution fails for a pool of
servers, the service might break itself. To be on the safe side, try
restarting Chrony in these instances, too.

Setting the server list to be empty is useful e.g. for hardware-only
or virtualized reference clocks that are passed through to the system
directly. In this case, initstepslew has no effect, so don't emit it.

Part of #49783. NextCloud tracks in its `config.php` the application's
state which makes it hard for the module to modify configurations during
upgrades.
It will take time until the issue is properly fixed, therefore we
decided to warn about this in the manual.
This PR addresses two things:
* Adding a basic example for nextcloud. I figured it to be helpful to
add some basic usage instructions when adding a new manual entry.
Advanced documentation may follow later.
For now this document actively links to the service options, so users
are guided to the remaining options that can be helpful in certain
cases.
* Add a warning about upgrades and manual changes in
`/var/lib/nextcloud`. This will be fixed in the future, but it's
definetely helpful to document the current issues in the manual (as
proposed in https://github.com/NixOS/nixpkgs/issues/49783#issuecomment-439691127).
This allows, finally, proper detection when postgresql is ready to
accept connections. Until now, it was possible that services depending
on postgresql would fail in a race condition trying to connect
to postgresql.
When reworking the rspamd workers I disallowed `proxy` as a type and
instead used `rspamd_proxy` which is the correct name for that worker
type. That change breaks peoples existing config and so I have made this
commit which allows `proxy` as a worker type again but makes it behave
as `rspamd_proxy` and prints a warning if you use it.
This commit adds an assertion that checks that either `configFile` or
`configuration` is configured for alertmanager. The alertmanager config
can not be an empty attributeset. The check executed with `amtool` fails
before the service even has the chance to start. We should probably not
allow a broken alertmanager configuration anyway.
This also introduces a test for alertmanager configuration that piggy
backs on the existing prometheus tests.
The default of systemd is to kill the
the whole cgroup of a service. For slurmd
this means that all running jobs get killed
as well whenever the configuration is updated (and activated).
To avoid this behaviour we set "KillMode=process"
to kill only slurmd on reload. This is how
slurm configures the systemd service.

Otherwise netdata will not find python modules.
To make sure netdata still pick up our setuid version of apps.plugin
we rename the original executable.
These days build systems are more robust w.r.t. to concurrency.
Most users will have at least two cores in their machines.
Therefore I suggest to increase the number of cores used for building.

Based on reports X wouldn't start out of the box and seems OK now.
In case there are still some problems, we can improve later.
I checked that nixos.tests.virtualbox.* still succeed.
