Yes. But I was curious what could have assigned a UUID to /dev/sda. And I found
it. Making a nilfs2 partition on /home the evening before, lsblk -f reported
the same UUID for /dev/sda and /dev/sda4!

After reformatting /home with good ol' XFS and a reboot, /dev/sda no longer has
any UUID, and all is good.

Now that was REALLY weird. WTF??

Looks like a serious problem with nilfs-tools.
