If you have time to submit a diff or patch to amanda-hackers that would be
very helpful.

Hello, here I'm again.
Well, the solution for my problem is really simple, but I have had to
read the script first as Paul Bort implied.
FreeBSD's 'mt' command reports in a different way than other OS' mt
and for that, the variable $ONLINEREGEX in the script chg-manual contains
no identifying expression to detect that a tape is 'online'. I added there
a string which is only present if a tape has been sucessfully loaded into
the drive and now, voila, it works fine also for FreeBSD driven UNIX boxes
;-)
Thanks a lot ...

:>OK, I'm getting closer. The reason that it keeps asking for a tape in the

:>Should really have a slot number in the <>, but doesn't. The variable
$used

:>
:>OK, it looks like the line before the "loaded" message is the relevant
one:
:>
:>used=`$MT $MTF $tape status 2>&1 | tee -a $dbglog | $EGREP "$ONLINEREGEX"`
:>
:>This is placing the status message in the log, but it looks like no status

:>
:>My status messages look like this:
:>
:>[amanda@tape configdir]$ mt -f /dev/nst0 status
:>SCSI 2 tape drive:
:>File number=0, block number=1, partition=0.
:>Tape block size 0 bytes. Density code 0x0 (default).
:>Soft error count since last status=0
:>General status bits on (1010000):
:> ONLINE IM_REP_EN
:>
:>I think that the grep is looking for 'ONLINE' and not finding it in your
:>status message, so it doens't think the tape drive is ready, and asks you
to

:>
