I finally managed to make a snapshot of that with mksnap_ffs, mounted it as an md, but it turned out to be just a snapshot of / and not dumpable anyway. tar is generally useful, especially with trees like /home where there tend not to be any hard-linked files, here anyway. But I'd miss dump. I learned some new things, but C wasn't one of them (sorry, Adrian :) cheers, Ian
