You can do a ufsdump of root (/) and restore it to another box by booting from DVD into single-user
and then accessing the ufsdump from tape or nfs handle or wherever you stored it. Before the restore you can format disk, set slices, mount the empty disk (typically onto /a) and restore the filesystem.
Be aware though that you may well have to tweak a number of things whilst in single-user after the restore such as boot block, /etc/vfstab, system file, and very likely the device nodes for drives, before the system will boot. Then modify the name of the network interface, etc. I've detailed this on a number of threads here in the past so search for it or post back here with your questions.
