Bug#504397: ext2_or_ext3_boot check fails when /boot is RAID
We have a partman check that ensures on some devices that the /boot
partition is the 1st primary partition. Unfortunately this check
fails when /boot is a RAID device, but it's actually valid for /boot
to be a RAID1 device (as long as its physical partition is the 1st
primary partition).
There's currently no good way to map the RAID device to its physical
partition to performs these checks, so I was thinking of applying a
patch for lenny to skip the check if the /boot device is RAID1.
OK to apply? (I don't think many users are affected by this, so this
isn't crucial)
