jbjohnso 8250bc1673 Have RedHat installs reduce risk of overwriting SAN volumes. The strategy:
BIOS drive 80 is chosen if at all possible (don't know EFI way yet)
Failing that, first virtio block device
Failing that, then first block device served by ata_piix4, ahci, megaraid_sas, pmcraid
Failing that, first mptsas or mpt2sas
Failing that, first block device
