RAID 1 without specifying devices

[Johnny Ljunggren <johnny@xxxxxxxxx>]

Hello all

I'm usually installing my systems with Software RAID 1 and have up to 
now specified the hard drives to be used by their device names (/dev/hda 
etc...), ie
part raid.01 --bytes-per-inode=4096 --fstype="raid" --ondisk=hda 
--size=10000

Is there a way to create the RAID without specifying --ondisk?
There will always be two disks on these systems, but not necessarily in 
the same position each time.
