The partitions don't even need to be the same names. To do a "clone", I cd into the target filesystem (/, /var, /usr) and use 'restore -ruf dumpfile'. Usually the dumpfile is on an NFS mount. > I will need to install a base OS on the new systems first, so I can > partition the drives and be able to connect tot the box, the second question > is, when I use restore, will it overwrite the kernel, if so, can I protect > the kernel from being overwritten? You could use the live filesystem CD (#2) or a FreeSBIE CD also, but I usually just do a minimal install. There may be an error when restore attempts to overwrite the kernel; can't recall. However, I rebuild the kernel after the system has been cloned to be sure it's in sync with the current source on the machine. > The third question is, can I, should I, use rsyn insted of dum and restore? dump and restore are the right tools for this case. -Warren Block * Rapid City, South Dakota USA
