This flake defines the shared configuration and packages that I want all of my machines to share. It is also set up so that other flakes (e.g., a private one for work) can inherit from it easily.
archetypes- System-specific config that is shared among all machines of that system type
hosts- Host-specific config
modules- Spot for things like home manager config that will be common across all machines
lib- Exposes custom functions for easily defining configurations in other flakes
flake-parts- Defines exports and also the actual systems this flake manages
I have been using a fully terminal based development environment for a few years now, and I was starting to get really frustrated with having to update my personal laptops and servers every time I made some kind of change to my workflow.
Instead, I decided I would pour hours into learning Nix well enough to write this and save dozens of minutes every year!
Jokes aside, this setup has been serving me well and I intend to continue improving it over time. Obviously, it is highly tailored towards my own needs, but perhaps the general structure could be useful to someone else.
