#./hosts/hardware/FredOS-Kayla.nix
#
# Same hardware as FredOS-Gaming apart from the drives (and the monitor, which
# Plasma's own display settings handle — nothing to pin here). Kept off the
# CachyOS kernel/attic substituter the gaming box uses: stock
# linuxPackages_latest from common.nix, one less input to babysit.
#
# The fileSystems below are PLACEHOLDERS — this evaluates but will not boot.
# Run `nixos-generate-config --show-hardware-config` on the machine and paste
# the real UUIDs over them, then push.
