* Resolves#118
* Leverage flakes to manage package sources & hashes
* Update documentation with an example.
* Add `mkVersion` function to autogenerate a version string.
* Add srcs package via overlay containing all sources defined in
_pkgs/flake.nix_
* Extend `flk update` with the ability to only update the given input
* Leave importing to nixpkgs module implentation. Provide a path
instead; resolves#136.
* Allow profiles which are not lambdas but simple attribute sets,
relaxing the constraints a bit.
* Update profile README.md
* defaultImports -> mkProfileAttrs: allow importing subprofiles even
if parent directory does not contain a default.nix.
* Update the readme to pull from cachix first, so users don't have to
build nix.
* Pull `nixFlakes` from override for slightly newer ui, and consistency
for users who change the nixos flake ref to something newer.
The bash wrapper was causing issues with deploy-rs and the
experimental-features option in the config was causing hercules-ci to
spit out a bunch of junk in the logs. Patching nix with the default
values required for flakes fixes both of these issues.
Managing servers remotely is a big usecase, and deploy-rs is a flake
first deployment tool. By default, all nixosConfigurations are also
setup as deploy-rs nodes.
You'll still need to do some manual ssh setup, but other than that, the
system is ready to deploy.
Users may wish to change the default value of override and nixos
inputs. If they do so, we want the registry listing to reflect the
proper ref names afterwards.
Also create a shell alias to easily search every flake in nix.registry.
