It can > scan the device, and only dump files within the specified tree. Interesting idea. I think it might become a little confused about hard-linked files where part of the links falls outside the desired dump tree, but it might be worth the while. This feature is about what people do most miss on dump(8). (The ability to exclude specific subtrees would be even more cool, so you can e.g. exclude your /var subtree when dumping / where /var is on /.) > I seem to recall someone here saying that it wouldn't take much to > add this to the FreeBSD dump program. Well, if somebody has it done, i'm certainly interested! -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
