summary: copy root -> boot

Many thanks to all who replied to my problem. My original email is at the
bottom. The solution that
worked was sent by Brett Lynn. His suggestion was as follows:

boot from cdrom
mount the root file system as /a
remove /a/dev and /a/devices
copy /dev -> /a/dev
copy /devices -> /a/devices
copy /etc/path_to_inst -> /a/etc/path_to_inst
drvconfig -r /a/devices -p /a/etc/path_to_inst
disks -r /a
shutdown
boot -r (and cross your fingers)

You have to do it this way because the kernel relies on some device
paths to find files which puts you in a chicken and egg situation. I
think the reason the boots fail just with copying things is that the
path_to_inst file contains hardware instance paths that change between
the machine types.

Thanks again,
Greg Mani
