Some kernels report devices in /proc/partitions differently causing the FAI disk
detection to fail. I'm sure there's some kernel option for this, but I've no idea what
it is.
FAI expects /proc/partitions to be of the format:
pilsner:~# cat /proc/partitions
major minor #blocks name
3 0 39082680 hda
3 1 32098 hda1
3 2 104422 hda2
3 3 1 hda3
3 5 530113 hda5
3 6 104391 hda6
3 7 16033 hda7
3 8 2048256 hda8
3 9 2048256 hda9
Whereas, some kernels report it as:
pilsner:/tmp/fai# cat /proc/partitions
major minor #blocks name rio rmerge rsect ruse wio wmerge wsect wuse running use
aveq
3 0 39082680 hda 6 18 48 110 0 0 0 0 0 110 110
3 1 32098 hda1 0 0 0 0 0 0 0 0 0 0 0
3 2 104422 hda2 0 0 0 0 0 0 0 0 0 0 0
3 3 1 hda3 0 0 0 0 0 0 0 0 0 0 0

3 8 2048256 hda8 0 0 0 0 0 0 0 0 0 0 0
3 9 2048256 hda9 0 0 0 0 0 0 0 0 0 0 0
So, here's a patch that works for both cases:
