In very short, I have a NixOS install with an /etc/fstab using UUIDs. However, my bulk drive died. I have backups, the data is not the problem.

But I can’t boot NixOS without the drive. It throws me into an emergency shell, in which I can’t edit /etc/fstab (read-only FS) and since I’m in emergeny mode, nixos rebuild doesn’t work either (seems to be mostly a network issue).

So, what’s the best, non-reinstalling way to fix that?
