For some reason, StateDirectory does not work very well with the sqlite format.
This acts as a workaround of such, and allows the service to alternatively work
in an alternative, user-created directory if the issue does arise again.
See https://github.com/muety/wakapi/issues/731 for context and
motivations for this change.
Using implication here (->) causes the assertions to fail haphazardly due to the ordering *implied* by the operator. By using AND, we avoid this case. Unsurprisingly, this was caught by the NixOS test.
Currently the NixOS module for Wakapi will create the database
automagically if the user has database dialect configured in the Wakapi
configuration file. By all means, this is undocumented behaviour and an
anti-feature.
This MR adds a database.createLocally option that allows the end-user to
create auto-creation behaviour, and lays out groundwork for automated
database setups for different database dialects supported by Wakapi.
