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.
Adds a NixOS module which allows using mandoc as the main manual
viewer. It can be used as a drop-in replacement for documentation.man
which relies on GNU's man-db and provides more or less the same
features.
The generateCaches option requires a different implementation for
mandoc, so it is hard to share code between the two modules -- hence it
has been implemented separately. Using both at the same time makes
little sense and wouldn't quite work, so there's an assertion to
prevent it.
To make makewhatis(8) index manual pages which are symlinks to the nix
store, we need to set READ_ALLOWED_PATH to include
`builtins.storeDir`. For background and discussion see:
https://inbox.vuxu.org/mandoc-tech/c9932669-e9d4-1454-8708-7c8e36967e8e@systemli.org/T/
It may be possible to revert the move of `documentation.man.manualPages`
later. The problem is that other man implementations (mandoc) want to
generate their index databases in place, so the approach taken here
doesn't translate super well.
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.

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.
Fix a typo in the kea-dhcp-ddns-server unit definition, and add a
KEA_LOCKFILE_DIR environment variable without which kea daemons try to
access a lockfile under /var/run/kea path, which is prevented by
systemd's ProtectSystem (or one of the other Protect*) mechanism.
kea-dhcp-ddns-server doesn't react to updates from dhcp4 server at all
without it.
