I want to write a small text file (about 200 bytes) to the
beginning of a tape. Then I write several partitions of the disk to
the same tape. Some time later, I want to read back the text file and
the partitions on the tape.
The command to write is (ignoring error checking):
e.g.
mt -f /dev/rmt/0cn rewind
tar cvf /dev/rmt/0cn file1
ufsdump 0uf /dev/rmt/0cn /
ufsdump 0uf /dev/rmt/0cn /usr
....

Some time later, to read back the data:
mt -f /dev/rmt/0cn rewind
tar xvf /dev/rmt/0cn file1
ufsrestore rf /dev/rmt/0cn
ufsrestore rf /dev/rmt/0cn
....
