The dump program on our 4.1 bsd system has the undocumented feature that it can be given a path name instead of a filesystem name. The path name must be a directory entry in fstab, dump looks in fstab to get the raw filesystem name. For example, if I have the following line in /etc/fstab, /dev/up0h:/va:rw:1:2 Then the following to calls to dump have the same effect. dump 0u /dev/rup0h dump 0u /va This is a nice feature if you have your dumps set up in a shell script for an operator to use. When you have a head crash (we have had two in the last month) you do not need to rewrite the script when the system is reconfigured. sid@LINUS.UUCP

Dumping by the name of the directory where the filesystem is mounted rather than absolute device name is even nicer if you want to do backups on a number of machines, each of which has the same set of mounted filesystems but on different hardware, without needing a different shell file for each machine.
