The only thing I would add to this is to run your OS off of a CD
distribution or a different HD than your source or destination disk.

I would also add "p" to the slave side of the tar to preserve
permissions. ie. "tar xpf -"

This is one place where dd would be appropriate. Assume master disk
is /dev/hdb and destination disk is /dev/hdd. You have grub or LILO
on the MBR of /dev/hdb.
dd if=/dev/hdb of=/dev/hdd bs=512 count=1
