Is GPT partition automounting possible? (such that /dev/disk/by-id/... is not necessary)

Help

On arch linux, if the partitions are partitioned by GPT Partition type UUID [1] correctly, systemd-boot automatically discovers and mounts the partitions correctly [2].

This even works with luks-encrypted root partitions.

I never had to generate an /etc/fstab nor did I ever have to fiddle with /dev/disk/by-uuid/

I used truly the same system, could clone it to a new ssd’s root partition and plug and play. [3]

However, on nixos I have not found such an option. The hardware-configuration.nix embeds hardware-specific disk uuids, which is entirely unnecessary.

Is GPT partition automounting possible on nixOS?

}

The full autodiscovery generator is not yet available for nixos.

You can do your [3], and reference the partitions in filesystems.* using /dev/disk/by-label paths. The installer has picked the disk paths via (probably) /dev/disk/by-id, in part because it’s very possible to have multiple disks/partitions with the same label, but you can of course edit that to fit your own practices and preference.

Thank you for the swift reply.
Using labels is a temporarily sufficient workaround.
