[sclug] pmount and umount in kubuntu *RESOLVED*

[John Stumbles]

I wondered why my followup query* to Chris And Alex's replies to my 
original question elicited no responses: I've just realised I did a 
'reply' and thus sent it only to Chris instead of the list.

GAH!! I HATE THE BROKEN BLOODY From: / LACK OF Reply-To ON THIS LIST
</rant></foam>

OK, I feel better now. :-) Sorry, I know we've had this debate before.



Anyway, I found the answer to the how-to-umount-from-pmount problem: 
pumount. D'oh!


FWIW I also found that to allow other users to pmount/pumount devices 
they have to be members of plugdev, which wasn't self-evident to me :-)

Nope:
john at stonehenge:~/pix$ umount /media/sda1
umount: /media/sda1 is not in the fstab (and you are not root)

that works, and I can also sudo umount /dev/sda1, but why do I need to
be root? I _mounted_ it as non-root, and I can unmount it as non-root
via the gui so there must be a way to do it at the command line or in a
script. Mustn't there?


(I want to write a script to mount a camera's flash card, read the
contents, process them, then unmount the card again. I want this script
to be runnable by other users on my system who are not sudoers.)
