Hi ,everybody. It's long time sice I came here at last time, I hope following script will be useful to everyone.
-------------------------------------------------------------------------- #!/bin/sh # program to copy root & usr partitions and create a new bootable disk # Note that this script is limited to SCSI drives, and only those # on controller 0. # It makes the root & usr filesystem on partition 0 for target drive # and install sash, ide & fx in the volume header of the target drive. # usage ./clone_disk 0 1 0 2
