I suggest you probably also want different host names.
I had a similar task to create clones of a machine 'phoenix00'
as machines 'phoenix01' to 'phoenix14' for which I wrote (and used)
the attached script.
The original machine had ip 192.168.3.237 and the clones were to have ip
addresses in the range 192.168.3.211 to 192.168.3.249
The original system is in partitions ad0s1a, ad0s1e, ad0s1f and ads1g with
swap on ad01b.
To use the script attach the (identical) drive to as ad1 to 'phoenix00'
and call the script (as root):-
(There is no secondary IDE port on the machines in question which might have
been somewhat faster)
# ./clone.sh ip mach
where ip is the last group for the required ip and mach is the numeric part
of the clone host name 'phoenixNN'.
The script copies the MBR and disklabel from ad0 to ad1 and then creates the
file systems and copies data with dump and restore. The cloned configuration
file /etc/rc.conf is edited using 'sed' to update the ip address and hostname.
Plug the cloned disk into the new machine (as ad0) and it should boot without
problems (remembering to fix master/slave links on the disk).
Adapt, use and enjoy.

Probably but would need more preparatory work.

I don't know Knoppix but if you have large disks any literal byte to byte
disk copying will take quite a while. Should also be possible with dd
but if the source is mounted rw at the time the copy will not appear to be
clean when booted in the new machine.
