Red Hat Bugzilla – Bug 134564
Logging out a user (not root) should trigger a umount of all the volumes he/she mounted

<copy-paste from fedora-devel-list> While there are so much chattering about automounting, security considerations of the new fstab "console" tag etc., i have as a systems administrator withnessed one thing - with something as old as floppyes. People mount up the floppy (acctually, they have no clue that they are mounting it, they just click the nice little "floppy" icon), get their files, pull out the floppy (without umounting), and logs out. Then, 2 minutes later, another user logs in, pulls up his/her floppy, and... the floppy is mounted. Cant get it umounted, and can't mount his/her floppy. Grr... Reason that there is a problem with floppyes and not other removable storage, is of cource that floppyes is the only removable storage that the user can pull out without the system gets the message - if you pull an usb mass storage plug, it gets umounted (and it is mounted "sync" so you probably won't loose data either). If you try to eject a cd, it wont come out - untill you umount it (this is really frustrating to new users as well - the "eject" button should umount the cd and eject it, and if it is buisy, tell dbus to tell gnome to display that popup we all loved in fc1) But what if all volumes that the user mounted when he/she was logged on, automatically got umounted when the user who mounted it logs out? That would solve it. </copy-paste from fedora-devel-list> Yes, i'm lazy. Dont shoot me. Alan told me to post an RFE to bugzilla, and it somehow landed on basesystem. Feel free to move it :)
Sounds ok. We would have to special case root so if you were logged into an X session as root (rare but some people do it) it doesn't unmount. Pictures dance in my head of g-v-m bringing down '/' ;-)
if (uidnumber > 0) { system ("umount -a"); } Something like that in the shutdown code should umount every not-in-use volumes the user has permissions to umount. But i see two problems with this approach: - What if something bad happens to gnome-volume-manager - What if the user hits control-alt-backspace (same as #1?) - What if the user already has "pulled" the floppy, or some stupid app is running on it? (*KILL* it! Or simply just do a lazy umount, and wait for the app to die of its own (the users) stupidity?)
The way it will work is a bit more complicated. Can't say if it will get into the release or not since this was requested so late but I'll see what I can do. Basicly short term what will happen is we will itterate over the list of mounts lazy unmounting all mounts with user=<the session user>.
Well, I guess it is your lucky day as I have just tested this and it already works out of the box in Rawhide.
:) Thats nice! => it will work like that in fc3 :) How does it work?
Rawhide is the development version which will become FC3. gnome-volume-manager handles unmounting user mounts when the session gets logged out. I tried this with a USB memory drive and a floppy.
Yes i know that. But will it work if the user hits "control-alt-backspace" to log out as well?
