The nixpkgs is now assumed from the outside. This allows for the config
to have more control with the nixpkgs to be imported with the
home-manager configuration.
Now we can finally easily declare the nixpkgs channel for individual
images. This is nice once I've expanded the images for other purposes
such as physical hosts (for homelabbing).
Unfortunately, this is where I realized that stable channels are not
exactly "Debian-stable" and the best way to handle security is to have
an update cadence that is relatively quick.
Additionally, I have also made a declarative version of the project
cluster with a neat little file at `images.toml`. This is way better for
individually referring to hosts from the host directory compared to the
old way.
I forgot I set the home-manager values only to
`homeManagerConfigurations` in the flake output. It should be added to
the hosts configuration with the `home-manager.sharedModules` attribute.
It doesn't make sense to put them into separate file anymore since there
is always only one location that uses it. The flake utilities have been
changed also with the updated version of the functions from its inputs.
Now that `system` top-level attribute in `configuration.nix` is
documented and comes with additional options now, we'll have to move the
system configuration into a new namespace. This is just the easy way
out.
There are now other user configs that make use of different attributes
from the flake itself. It is better to make `extraSpecialArgs`
configurable at this point.
- Add custom GNOME configurations with dconf keyfiles.
- Refactoring in certain parts of files especially with handling merging
and importing of modules.
I revisited NixOS this week and I've rewritten my NixOS config from
scratch. I must say I really like Nix flakes. For whatever reason it
just clicked and I understood more programming with Nix despite my
previous experience which is not good. Could be just the fact I had a
break for a long time from completely using Nix (I still used it on
non-NixOS distros).
Eh... I still took some things from the original inspiration of this
configuration so there's that.
