Comment 12 for bug 1735839

Manually checked on a physical node with 1 device after replacing changed curtin files on a MAAS node (the code isn't in -proposed yet at the time of writing), seems to work:

ubuntu@redacted:~$ blkid
/dev/sda1: LABEL="root" UUID="2b708114-354c-4ece-9d2e-3b7c202cbf17" TYPE="ext4" PARTUUID="18b7f148-01"

I'll try to get a node with an NVMe device (or create a virtual one) and check there as well.
