I've sent Luigi one. It is probably just as quick and dirty as the others. (It is already in the list archives, from a previous incident.) > Does dumpfs exist on FreeBSD ? Yes, but it (currently) doesn't take an alternate superblock number to use. This is becoming a FAQ. Two enhancements to tools that might help would be: o making newfs add superblock numbers to /etc/sbtab like HP-UX does (caveats on / being mounted read-write etc) o adding an option to dumpfs to tell it to find superblocks If there is (some sort of) consensus I'll write some code. (More promises, yikes.) Regards, Giles
