Detecting boot drive

[Andrew Simpson]

have you thought about trying to find it by UUID or Label?  I had a similar
issue in a kickstart where I could not determine the boot drive while
making a USB boot image.  I ended up formatting the drives with a specific
LABEL and using that in the kickstart instead of using sda/sdb/etc...
