for clarity's sake, expose which function uses final and prev, so that
people can have a clearer understanding how they relate to each other
in terms of dependencies.
also a simple `{ lib = final; }` probably does not warrant a complete
callLibs obscurization.
231: Move flake implementation logic to lib r=nrdxp a=Pacman99
This is a simpler version of #218 that moves flake logic to lib and adds a module to evaluate devos. This DOES NOT support out of tree usage, so if you were following any of the previous PR's, the doc sections/examples to use devos as a library will not work. There is work to make a cleaner api and only then will out of tree support work. Until then, this is still useful to simplify devos and clean up a lot of the implementation logic.

224: Allow for directories in module-list r=nrdxp a=Pacman99
fixes#221
building on #222 this PR improves the lib functions pathsToImportedAttrs and pathsIn. First to add support for directories. This does not support actually passing a file in a directory, so `./matrix/default.nix` won't work but `./matrix` will - I should probably document this somewhere.
Also I moved the filtering for nix files to `pathsIn`, since its only necessary for auto-import. We can assume that users would pass proper files in `module-list.nix`.

217: lib/mkPkgs: don't import external files and get inputs as argument r=nrdxp a=Pacman99
Changes mkPkgs to take extern, overrides, and pkgs as an argument. This improves their ability to be used as lib functions.

220: Drop flattenTreeSystem and use custom function for filtering packages r=nrdxp a=Pacman99
I don't think we should flatten the system because if a user doesn't make a package a derivation in pkgs/default.nix we should trust that there is a reason for doing so. So instead this drops the flattenTreeSystem reference(and switches to flake-utils master branch) and replaces its usage with a custom function `filterPackages`. This function filter all packages that match three conditions;
- is a derivation
- not broken
- system is supported
In that order as to not cause errors when trying to reference non-derivation meta attributes.
And then also just dump *all* packages into legacy packages, so everything else is still accessible. I was considering removing the packages that are already in the packages output in legacyPackages, but I don't think its necessary since nix looks to the packages output first.

215: lib/pathsToImportedAttrs: discard string context in the names to prevent flake check error r=nrdxp a=Pacman99
So I learned about this myself while working on it. Nix has a thing called string context, where strings refer to various store paths that they used to contain. This is normally a good thing to guarantee purity, but flake outputs cannot contain store paths. So when `pathsToImportedAttrs` is passed a list of store paths, and is then used for a flake output, we get a very confusing error that the string refers to a store path - even though it doesn't look like it does!
I think its good to review this as a separate Pr, since it requires calling an unsafe nix builtin.

211: home-manager fixes r=nrdxp a=nrdxp
- [x] integrate nix-community/home-manager#1880 (to avoid duplicate commits, we'll wait a bit to see if this gets merged)
- [x] don't use all of `systemPackages` for `flk home`
- [x] test home-manager `activationPackage` and `flk home` as part of CI

219: lib/mkPkgs: reorder overlays to get access to devos lib(dev) r=nrdxp a=Pacman99
nixpkgs applies overlays in the order given. This PR moves the lib extension overlay to be first so all subsequent overlays can access `dev` which is the devos lib.

This is just for convenience, since the closuers are already in the
store. It might be helpful to be able to test out some things
of those deactivated profiles een on the iso isntaller.
