VMs were starving, many of the daemons were unable to complete their
tasks resulting in tests failures.
Turned off verbose output from k8s components as it consumes even more resources, and useful error messages actually drown in debug-clutter
1) Change start-type to ```notify``` when running MariaDB so that we don't have to busy-wait for the
socket to appear.
2) Do not manually create the directory under /run as we can get systemd to do
that for us. This opens up the possibility later for not having to launch as root.
`xsslock` (which was originally packaged in 6cb1d1aaaf)
is a simple screensaver which connects a given screen locker (e.g.
`i3lock`) with `logind`. Whenever `loginctl lock-sessions` is invoked
the locker will be used to lock the screen. This works with its power
management features (e.g. `lid switch`) as well, so the PC can be locked
automatically when the lid is closed.
The module can be used like this:
```
{
services.xserver.enable = true;
programs.xss-lock.enable = true;
programs.xss-lock.lockerCommand = "i3lock";
}
```
`statsd` is a daemon written in `node` to gather statistics over UDP.
The current test ensures that a port is open, but the basic
functionality isn't sufficiently tested.
This patch contains the following changes:
* Simplified port scanning (`waitForOpenPort` rather than `netcat` magic).
* Issue a TCP command to check the health of the `statsd` server.
* Simple script to check if `statsd` receives data over UDP and confirms
the basic functionality of the TCP interface on `8126` for admin
purposes.
In commit 17dd7bcd89 the systemd unit
generator now uses lndir instead of "ln -s", so we need to have lndir
available in the Nix store for the installer tests to be able to build
the units and thus the whole system.
This should fix the installer tests, although I have only tested it with
the "simple" subtest.

The original `nexus` derivation required `/run/sonatype-work/nexus3`
which explicitly depended on the NixOS path structure.
This would break `nexus` for everyone using `nixpkgs` on a non-NixOS
system, additionally the module never created `/run/sonatype-work`, so
the systemd unit created in `services.nexus` fails as well. The issue
wasn't actively known as the `nixos/nexus` test wasn't registered in
Hydra (see #40257).
This patch contains the following changes:
* Adds `tests.nexus` to `release.nix` to run the test on Hydra.
* Makes JVM parameters configurable: by default all JVM options were located
in `result/bin/nexus.vmoptions` which made it quite hard to patch
these parameters. Now it's possible to override all parameters by
running `VM_OPTS_FILE=custom-nexus.vmoptions ./result/bin/nexus run`
(after patching the `nexus` shell script), additionally it's possible
to override these parameters with `services.nexus.vmoptions`.
* Bumped Nexus from 3.5.1 to 3.11.0
* Run the `nexus` test on Hydra with `callTest` in `nixos/release.nix`,
furthermore the test checks if the UI is available on the specified
port.
* Added myself as maintainer for the NixOS test and the package to have
some more people in case of further breakage.
* Added sufficient disk space to the `nexus` test, otherwise the service
fails with the following errors:
```
com.orientechnologies.orient.core.exception.ODatabaseException: Cannot create database 'accesslog'
com.orientechnologies.orient.core.exception.OLowDiskSpaceException: Error occurred while executing
a write operation to database 'accesslog' due to limited free space on the disk (242 MB). The database

drive and then reopen the database. The minimal required space is 256 MB. Required space is now set to
256MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit) .
