[ale] SATA disk naming

[Jim Kinney]

The drive ordering is based  more on the device ordering from the pci bus
scan and sata init. Check what cat /proc/scsi/scsi says. I bet the new sdb
even though it's in a sata#3 socket has a lower lun than sata#2.

And yes, this is why the transition to UUID is happening for distros like
Fedora. I think Ubuntu also does drives by UUID as well. For some reason I
don't find UUID=c2a3c3bd-414c-4c30-a83c-38e69551808a easier to read than
/dev/sda
