This script is used to clone a system's boot disk onto another disk.
It assumes that both disks use separate root and /usr partitions,
that the clone disk is already formatted and partitioned,
and that it will use partition 0 for root, and 6 for /usr.

If this is not how you do things, you should modify the script to suit your
environment before running it (high end systems don't need ide in the volhdr).

It first uses dvhtool to setup the volume header.

Then, for both / and /usr, it does the following:

- uses mkfs to build fresh filesystem
- uses dump and restore to copy the filesystem
- runs an fsck to make sure everything went OK

It also sets up /etc/sys_id on the clone disk.
If you need any other files to be different, you'll have to edit them manually.

You should run clonedisk in SINGLE USER mode.
This keeps the copy clean, as the filesystem isn't changing underneath.
