This is a useful utility for monitoring network performance over time
using a combination of MTR and Prometheus. Also adding a service definition.

When startWhenNeeded is enabled, a brute force attack on sshd will cause
systemd to shut down the socket, locking out all SSH access to the machine.
Setting TriggerLimitIntervalSec to 0 disables this behavior.
In https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/merge_requests/153
the user target names for GSD components has been renamed for example
from `gsd-a11y-settings.target` to `org.gnome.SettingsDaemon.A11ySettings.target`,
and nowadays `gsd-*.target` are just symbolic links of `/dev/null` and will be
removed in the future.
At the same time, as mentioned in d27212d466,
we are adding `systemd.user.targets.<name>.wants` stuff here only because
systemd.packages doesn't pick the .wants directories. Nowadays those GSD components
are managed in `/etc/systemd/user/gnome-session@gnome.target.d/gnome.session.conf`
so it should be safe to remove them.
In this commit we also try to pick up those new .wants directories, see also

This never configured where SNI should log to, as it's up to the user to
provide the full sniproxy config (which can be configured to log to a
file).
This option only produced a ExecStartPre script that created the folder.
Let's use LogsDirectory to create it. In case users want to use another
directory for logs, they can override LogsDirectory or set their own
ExecStartPre script.
The systemd syntax is suprising to me, but I suppose it's worth being
compatible as people might be sharing it with other modules.
Our regexp is lenient on IPv6 address part, so this is actually
backwards compatible (i.e. you can put the scope at either place).
tracker looks in its directory tree for executable files
to make available as subcommands. Users expect to find subcommands
from tracker-miners package but that fails as they are in different
tree. We also cannot change the lookup path since tracker-miners
also depends on a library from tracker package.
Until we can break the dependency cycle on package level:
tracker -> tracker-miners -> tracker-sparql (tracker)
we need to work around it. I chose to set an environment
variable that overrides the subcommands lookup to a tree
symlinking files from both packages in GNOME NixOS module.

Fixes: https://github.com/NixOS/nixpkgs/issues/153378
When `privateRepos = true`, the service will not start if the `.htpasswd` does not exist.
Use `systemd-tmpfiles` to autocreate an (empty) file to ensure the service can boot
before actual `htpasswd` contents are registered.
This is safe as restic-rest-server will deny all entry if the file is empty.
link to search.nixos.org instead of pulling package metadata out of pkgs. this
lets us cache docs of a few more modules and provides easier access to package
info from the HTML manual, but makes the manpage slightly less useful since
package description are no longer rendered.
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.
in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.
One use case for Mattermost configuration is doing a "mostly
mutable" configuration where NixOS module options take priority
over Mattermost's config JSON.
Add a preferNixConfig option that prefers configured Nix options
over what's configured in Mattermost config if mutableConfig is set.
Remove the reliance on readFile (it's flake incompatible) and use
jq instead.
Merge Mattermost configs together on Mattermost startup, depending
on configured module options.
Write tests for mutable, mostly mutable, and immutable configurations.
Before this fix, if the listenAddress is set to something else than 127.0.0.1,
the service fails to detect that Elasticsearch has properly started and stop.
this set almost certainly shouldn't be touched by users, nor listed in
the manual. make it internal and use it only through the option path to
make clear that this should not be modified.
Other services such as minecraft-server and plex allow configuration of
the dataDir option, allowing the files stored by each service to be in a
custom location.

Does not set MemoryDenyWriteExecute as OpenJDK need to mark memory page as
executable. Does not set ProcSubset as /proc/cpuinfo and /proc/meminfo
are needed.
This commit introduces `services.adguardhome.settings` and
`services.adguardhome.mutableSettings`.
The first option allows declarative configuration of
AdGuard Home, while the second one controls whether changes
made in the web interface are kept between service restarts.

It breaks something inside of influxdb2, which results in flurry of errors like these:
> ts=2021-12-21T18:19:35.513910Z lvl=info msg="Write failed" log_id=0YZYwvV0000 service=storage-engine service=write shard=50 error="[shard 50] unlinkat ./L1-00000055.tsi: read-only file system"
I believe this is somehow caused by a mount namespace that systemd creates for
the service, but I didn't investigate this deeper.
