  i don't care if it is returned, i just wonder why it isn't
redirected to /dev/null like i'm asking it to do.

  i check via the mount command but as i've found out it
isn't really reliable because in fact it is mounting something
even if it isn't there.

  as it is i have to tell the camera to be unmounted via gio
because when i plug the camera in the automounting happens
even if i tell the system to not do anything.

  and yes, i'm annoyed at systems that don't do what you tell
them to do.  the reason i'm writing this whole thing is because
i dislike all the stupid assumptions and baked in crap that
the camera manufacturer wants someone to jump through.  no.  the
USB connection works as it should, leave me alone.  grrr!

  so i almost have my camera script done but there's these
last niggling bits i'd like to iron out.

  thanks for the suggestion about lsusb.  that will at least
get around the main PITA i'm hitting.  :)
