Hi

I am writing wrapper scripts for amdump and amflush which add some extra files 
on the tape after a normal dump/flush. It's working fine but I would like to 
make this consistent with the files written by Amanda, with one header block 
for the label/comment, so I can restore them with the same amdd command 
(skip=1). I'm actually doing this:

echo "AMANDA: EXTRA-START $start_date" | amdd bs=32k of="$TAPE" count=1
tar -cf - /extra/dir | amdd bs=32k of="$TAPE"
echo "AMANDA: EXTRA-END" | amdd bs=32k of="$TAPE" count=1

... which produce three distinct files on the tape. How can I merge the label 
and the tar file so I can restore it with:

ammt bs=32k if=$TAPE skip=1 | tar -xf -

?
Thanks
