The detection file was written before the machine ran NixOS, as an educated
guess at what a Dell XPS 13 9380 needs, and said so. Its contents now come
from nixos-generate-config on the running machine.
The guess was wider than the measurement rather than narrower: it named
thunderbolt, usb_storage and sd_mod, none of which the scan reports, and
omitted rtsx_pci_sdmmc. Nothing needed to reach the root device was missing.
Filesystem, swap, LUKS and microcode declarations from the scan are dropped.
The disk layout derives the first three and the hardware profile supplies the
last, so carrying them here would duplicate definitions that are produced on
every evaluation.
neogaia was installed from a configuration written before the hardware
existed, so several things are now knowably wrong rather than guessed.
Adopt the upstream hardware profile for this laptop, which fixes deep
sleep, thermal management and the touchpad driver. Bound the store, the
retained generations and the boot menu, none of which have a limit today.
Declare the commit identity, which currently lives only in one checkout.
Grow the EFI system partition, which holds around seven generations at
its present size and cannot be enlarged in place, since the encrypted
container immediately behind it would have to be relocated. That makes a
reimage the only practical route, and the cheapest moment for one is now.
It doubles as the reproducibility test of the install documentation.
