Suggestions??? 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. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
