Working nixos-anywhere directly to nocix-amd-legacy-sexcore

This was essentiall an OS wipe, adding root authorized keys, then
running nix-anywhere out of the main flake. Saves a bunch of steps which
is really nice.

I removed the data disk from the disko config in the hopes it would
solve a problem that looked like:
