I don't think that this is causing the installer's bug, as usually people are
creating only xfs partitions with it.
Anyway the same bug seems to be triggered when (re)installing an xfs kernel
rpm on a solely xfs system and then rebooting. I would consider the installer-
with-grub-bug only an indicator for some nastier bug (I can live without an
installer, but not with something ticking under my data ...).
