Cool - nice to know!

Hmm - I wonder why this causes the partitioning to fail!? A quote from one of my
installations of a "normal" system, actually a dom-0:
--------------------------------------------------------------------------------
Partitioning local harddisks
setup_harddisks version 0.35fai
Probing disks:  /dev/sda
Disks found: sda
sfdisk: ERROR: sector 0 does not have an msdos signature
 /dev/sda: unrecognized partition table type
No partitions found


Using config file: /fai/disk_config/XEN0
Creating partition table: LC_ALL=C sfdisk -q  /dev/sda < /tmp/fai/partition.sda

sfdisk: ERROR: sector 0 does not have an msdos signature
 /dev/sda: unrecognized partition table type
No partitions found
Creating file systems:
  mke2fs -q -j /dev/sda1
  mkswap  /dev/sda2
  mke2fs -q -j /dev/sda3
  mke2fs -q -j /dev/sda5
  mke2fs -q -j /dev/sda6
  mke2fs -q -j /dev/sda7
  mke2fs -q -j /dev/sda8
  mke2fs -q -j /dev/sda9
  mke2fs -q -j /dev/sda10
  mke2fs -q -j /dev/sda11
Write fstab to /tmp/fai/fstab
Write FAI variables to file /tmp/fai/disk_var.sh
Calling task_mountdisks
--------------------------------------------------------------------------------
So it is telling me the same, but nevertheless continues to work; actually it is
to be expected that there is not partition table on a new set of harddisks...

HTH,
Michael
