this replaces niv with nix flakes, attempting to preserve the old
structure as much as possible. Notable caveats:
- I'm not sure if flake inputs expose version information anywhere, so
the version in pkgs/mattermost/default.nix is now hardcoded.
Confusingly, this appears to trigger a rebuild. Maybe I've missed something.
- a lot of the old-style host.nix & deploy.nix machinery in nix-hexchen
does not work with flakes, and their newer replacements are not exposed
by upstream; I've put basic imitations of the relevant parts in this repo
- (in particular, directories in hosts/ won't become deployable configs
automatically)
- parts of the code are now probably more complicated than they'd have to be
- old variables names were preserved; confusingly, this means the flake
inputs are still called "sources"
This simply updates nixpkgs to 21.11 (along with a general update of
other sources), then follows the hints given out in the build process
until everything (on parsons) ran through fine.
Some things to note:
- syncthing's declarative config is gone. Instead, declarative and
non-declarative configuration can now be mixed, but with
`overrideDevices` set to true, it _should_ ignore non-declarative
settings and basically behave the same as before (or at least that's
how I understood the documentation on that)
- some postfix options now require a lib.mkForce, since the mail module
also wants to set them — we should probably look into if the mail
module has nicer ways of handling our settings now (which I didn't
do)
- we no longer import the vaultwarden module from unstable, since it's
included in nixos 21.11 as-is. We _do_ still import the vaultwarden
package from unstable, since downgrading sounds like a bad idea.
- nix build will print a warning that `literalExample` is now
depricated, but we don't seem to use that — I guess at some point
we'll have to search through our sources if it doesn't go away
This was not yet deployed, and should probably considered a
work-in-progress.
Building Nixda currently fails decklink seems to have disappeared.
