I wouldn't have expected anything like this!
another alternative, since it's likely that the contents of /mnt/music could
change (I know mine does), why not do this.
umount /mnt/music
touch /mnt/music/SENTINEL
then do
if [ -f /mnt/music/SENTINEL ]
then
echo "Music share is not mounted!"
exit 1;
fi
#run your script here
the only way SENTINEL will appear is when the NAS is *not*
mounted. And this protects whatever you are using as your SENTINEL
from inadvertent deletion.
