Laniservu Nix Flake
To build an image which you can flash to USB disk:
nix build .#nuc-router-image -o result-nuc-router
Then you can write the resulting result-nuc-router/nixos.img to eg. USB disk
with something like:
dd if=result-nuc-router/nixos.img of=/dev/<DISK> bs=32M status=progress.
(Beware that you use right disk for of= parameter so you don't overwrite your
hard disk!)
Run:
nixos-rebuild --flake .#nuc-router --target-host root@nuc-router --fast boot
