The errors are most likely from wezterm-mux-server trying to start a
shell. This could be configured but it is better to treat this service
similarly to SSH servers.
Apparently, it doesn't really log the errors in the journal so it can
make the service failed for no reason. It can be configured to redirect
it to journal.
I didn't realize `network.target` is very ambiguous. The next best thing
for booting up the service after the system is up is `default.target`
but we're being explicit here for NixOS services just to make sure.
It was supposed to create the directory if it wasn't found which is
self-defeating. In any case, it will still fail if the directory is in
the way of an unmounted device.
There is the `--paths` option for that purpose. It also eliminates the
workaround for creating the directory before starting the service for
newly-bootstrapped systems.
The several hardening options have also been corrected.
Structure-wise, it is pretty similar to the gallery-dl service. It was
about to be combined into a bigger service module as a dedicated service
for multimedia archiving but it is better to have them modularized in
the long run.
While it is easier to maintain the modules by prefixing them all with
`modules`, it is not easy when used from other flakes and/or modules.
This is my attempt on making it easier with appropriate namespaces.
