Comment 4 for bug 687501

So the only way to get around this is to down the standby path and install.
Then the customer would have to install multipath-tools/boot, reconfigure
their fstab to use scsi ids or /dev/mapper/ paths, pick their device handler,
rebuild the initramfs and update grub as well.

Lot's of room for error here, even I mess it up on occasion.
