I don't know about removing a UUID, but you can assign a new one with GParted.
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.
