Other than mirroring techniques, the standard UNIX tools
for dumping and restoring systems partition-wise are
the dump and restore programs. There's a section in the
handbook about how to use them.
Another method is to use dd to make 1:1 copies of disks,
which usually works, but is not very "fine". :-)
I would go with dump/restore and have a custom-made
installer script handy which is executed after booting
the system (e. g. from CD, USB or LAN): It slices,
partitions and newfses the disks, applies labels if
needed, and restores from the .dump files as intended.
This is "fast enough" as it is a very safe solution.
