Yes, I did an install on /dev/hda1 and then configured hdb1 and hdc1 for
raid0 (for / mount) -- hdb3 and hdc3 (for /boot mount) on a couple of 20G
drives. (/dev/hdb2 and /dev/hdc2 are 128M swap). I mounted /dev/md0 as
/mnt/root and /dev/md1 as /mnt/boot. Then:
cp -ax /boot /mnt/boot
cp -ax / /mnt/root
Then, I wanted to remove the install disk. To do this, edit
/mnt/root/etc/raidtab and change references from hdb to hda. Configure
/mnt/root/etc/lilo.conf and /etc/mnt/etc/fstab and power down. Pull install
drive (old /dev/hda). Jumper /dev/hdb to now be master. Boot from a floppy
and run lilo. Reboot.
