grub2-probe error cannot stat devtmpfs

[downer]

Is anyone else having grub2 problems in Rawhide? I get this error that I can only fix with chroot using live CD:

# grub2-probe /dev/sda
grub2-probe: error: cannot stat `devtmpfs'.

Do I need to alter my fstab even more?

Or is the problem related to a bug about lvm not working with /dev/dm-0 ?

I was just wondering what's up with this grub2/grubby error in the last few days that also shows as a systemd error after an incorrect kernel update.
