* 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.
* Move extern lists to their own folder
* Move unstable package and module imports to their own folder
* Create a genPkgs function to avoid using legacyPackages for the whole
package set
* Move hmActivationPackages to legacyPackages
* Import attrs of profiles automatically with `defaultImport`.
* Refactor profiles to ensure all are functions returning a module.
* Add a suites.nix with collections of profiles.
* Add suites as `specialArgs` to modules.
* Add suite import to NixOS host.
* fix nixos-option
* use flake-compat for all backward compat concerns
* rebuild devshell after any nix file changes
* reexport system pkgs as legacyPackages
* provide lib flake output
* provide flake lib to nixos configs via `lib.flk`
* clean up flake.nix
master is only used in the context of `pkgs/override.nix`
and `unstableModulesPath`
and only within `./hosts`
Since overlays exists that are incompatible between nixos and master
at evaluation time (sic!), this together with #77 avoids evaluating
overlays against master all together.
since packages are exposed through output.packages by their own,
a second export through overlays.pkgs would be smudging the public api
of this repository.
