After enabling LUKS encryption, NixOS has a high probability of reporting an error on boot:

/dev/nvme01px is not a valid luks device

Multiple restarts can avoid this problem.

NickCao: When you have multiple disks of the same type(SSD/HDD), their disk number is random on every boot.

So the problem is caused by: https://github.com/ryan4yin/nix-config/blob/c4a28eb/hosts/idols/ai/hardware-configuration.nix#L48

  boot.initrd = {
    luks.devices."crypted-nixos" = {
      device = "/dev/nvme0n1p2";
      # ...
    };
  };

Every time I reboot, /dev/nvme0n1 is randomly assigned to any of my hard drives.
NixOS will start properly only if it is correctly assigned to my NixOS's drive.

Resolution: Replace device name with drive UUID in my configuration.
