core.nix is the new minimal layer: user, SSH, fish, nix flakes/gc,
locale, and a handful of essential packages. Suitable for any headless
host that just needs to be SSHable and manageable.
base.nix now imports core.nix and adds the day-to-day quality-of-life
layer: avahi, mosh, direnv, nix-ld, earlyoom, zramSwap, CLI tools,
and build toolchains. All existing hosts that import base.nix are
unchanged.
bootstrap is updated to import core.nix directly instead of
duplicating the config inline.
