No. Dump works always on a per-file-system base, that means, each dump volume is one file-system (or a part of it, if you do a level > 0 backup). This is why you would want to use the non-rewinding tape device for putting more than one file system on one tape, like dump 0uf /dev/nrsa0 / dump 0uf /dev/nrsa0 /usr dump 0uf /dev/nrsa0 /var and so on. If you like, let the last dump work on the rewinding tape device (/dev/rsa0), so it turns back to the beginning. To add more files to the tape, you can do positioning with mt (also with the on-close-do-not-rewind- tape-device, of course, because an mt -f /dev/rsa0 fsf will forward the tape and immediately rewind it on close). The rewind-device is the default.
