unable to fully boot after deleting home partition

[Andre Robatino]

> cd /
> tar cvf home.tar home
> umount home
> lvremove /dev/mapper/fedora-home
> lvextend -l +100FREE /dev/mapper/fedora-root
> resize2fs /dev/mapper/fedora-root
> tar xvf home.tar

Easy to reproduce in a VM after a minimal install with a large enough HDD that
it creates a separate home partition, then running the above commands.
