- So what's the problem? Use the norewind device after each dump, and they'll
- just keep getting tacked on the end of the tame. Use the /dev/nrmt* devices,
- rather than the /dev/rmt* devices.
-
- mt -f /dev/rmt0h rewind
- dump 0f /dev/nrmt0h /
- dump 0f /dev/nrmt0h /usr
- dump 0f /dev/nrmt0h /var
-
- etc. etc ad nauseum.
