The partitions don't even need to be the same names. To do a "clone", I
cd into the target filesystem (/, /var, /usr) and use 'restore -ruf
dumpfile'. Usually the dumpfile is on an NFS mount.

You could use the live filesystem CD (#2) or a FreeSBIE CD also, but I
usually just do a minimal install. There may be an error when restore
attempts to overwrite the kernel; can't recall. However, I rebuild the
kernel after the system has been cloned to be sure it's in sync with the
current source on the machine.

dump and restore are the right tools for this case.
