this started with emily pointing out to me that it's possible to
generate IP addresses for containers in Nix (hence no need to worry
about ever having collisions, as we had before), but then I thought,
hey, while I'm at it, I can also write a little container module so we
have a little less repetition in our configs in general (and a more
reasonable place for our custom evalConfig than just keeping it around
in flake.nix).
See the option descriptions in modules/containers.nix for further
details.
Apart from giving all containers a new IP address (and also shiny new
IPv6 addresses), this should be a no-op for the actual built system.
the bind mount module has been tweaked in a couple ways:
- rename hexchen.* to hacc.*
- rename bindmount to bindMount to make it consistent with usage in
the nixpkgs container module
- add a hacc.bindToPersist option as shorthand for prepending /perist
to a path via bind mount
the nopersist module has been shortened a little by moving
service-specific things which are used once out into the individual
service files, and removing those which we don't need at all (this also
means we get to loose a mkForce or two in case of mismatches between
hexchen's and our current config).
we decided to:
- get rid of unused packages
- simpify the directory layout since we only have one host anyways
- move our docs (such as they are) in-tree
