I have opted to use NixOS for my systems moving forward. You can read a bit more
|
|
|
|
|
about this move [[https://blog.gabrielsimmer.com/posts/from-guix-to-nixos][here]]. I haven't dabbled with custom configuration too much so
|
|
|
|
|
this is pretty close to the default configuration.

My goal here is to leverage the hardware configuration generated by

the NixOS to seperate out the specific-to-my-current-hardware configuration.
