Well, we have the following situation:
BOT EOM
|------archive 1--|-archive2-|--- archive 3 ---|
^
Then you do a mt -f /dev/nst0 fsf 1
|------archive 1--|-archive2-|--- archive 3 ---|
^
Assume you can now replace that archive 2 with archive 4
(which may be longer):
|------archive 1--|--- archive 4 ---|hive 3 ---|
^
Oops!
There goes your archive 3!
Thus this is not allowed.
You could delete all archives (i.e. archive 3 and archive 2)
and then append to EOM, then you'd have
BOT EOM
|------archive 1--|--- archive 4 ---|
^
This would obviously be very bad, especially if done
accidentally.
I don't know how that can be archived with mt and non-floppy
tapes. You may need a specialized program to edit the header
of the tape.
