Description of Problem:

If on a disk which we are installing there was present FAT-type partition
table then Disk Druid raises an alarm that "disklabel" type partition
is needed if one tries to create a new /boot partition but it does not
give a tool nor explanation how to achieve such effect.  Somebody not
well versed in intricacies of partitioning will have a hard time to figure
out that using fdisk instead s/he may get what is required.

It is nice that after all these years at last 'fdisk' does not crash
in such situation. :-)
