RAID 1 without specifying devices

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.

It's not pretty, but you can do this...

%include /tmp/kspart

%pre --interpreter /usr/bin/python
import os
import sys
import parted
sys.path.append('/usr/lib/anaconda')
import isys

drives = isys.hardDriveDict().keys()
drives.sort()

f = open("/tmp/kspart","w")

f.write( "part raid.01 --ondisk=%s\n" %
drives[0] );
f.write( "part raid.02 --ondisk=%s\n" %
drives[1] );

f.close()

I've made my installs generic by doing some work in the
%pre, then using
%include /tmp/partinfo in the command section.

something like this is what I use in the %pre

# Determine how many drives we have
set $(list-harddrives)
let numd=$#/2
d1=$1
d2=$3

# Use this scheme for two or more drives
if [ $numd -ge 2 ] ; then
cat << EOF >> /tmp/partinfo
YOUR SETUP --ondisk=$d1
YOUR SETUP --ondisk=$d2
EOF
else

# Use this scheme for one drive
cat << EOF >> /tmp/partinfo
YOUR SETUP --ondisk=$d1
EOF

fi

Thanks a lot to both Jason and Chip. I'll try them out
first thing tomorrow.
