Similar here. In most cases, the FreeBSD live system is completely
sufficient: run sysinstall, slice, boot loader, partitions, drop
to shell; mount USB stick, restore from files located there.

For automated cloning, there are good examples around that let
you boot from DVD or USB stick / USB hard disk and automatically
prepare the source disk, then restoring from files. This is a
common method especially via SSH, so a local media is needed only
for booting and maybe for preparing.

This means you bring up the minimal (installed) system first, then
do the restore? Why not do it right after the basic steps of
preparation right from the install CD?
