Bug 75895

User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020809

Description of problem:
The gconfd-2 daemon is run by many GNOME applications to manage configurations.
 Gconfd-2 remains running for some time after the application which used it
quits.  This allows other applications to use gconfd-2 without having to start
and stop the daemon too much.  This is a good idea.

The problem comes when a system tries to unmount a user's home directory when
the user logs out.  For example, pam_mount unmounts an encrypted home directory
then I log out of my system.

Gconfd-2 continues to run even when a user logs out.  This causes the unmounting
of the user's home directory to fail because gconfd-2 keeps the following files
open:

/home/user/.gconfd/lock/<random string>
/home/user/.gconf/%gconf-xml-backend.lock/<random string>
/home/user/.gconfd/saved_state

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Log in to system as mike
<pam_mount mounts /home/mike automatically>
2.  Run any program that causes gconfd-2 to execute (ie: galeon)
3.  Log out
<pam_mount fails to unmount /home/mike>
4.  Try to unmount /home/mike by hand.
	

Actual Results:  It is impossible to unmount /home/mike until:

gconfd-2 releases /home/user/.gconfd/saved_state

and later releases /home/user/.gconfd/lock/<random string> and
/home/user/.gconf/%gconf-xml-backend.lock/<random string>

Expected Results:  Gconfd-2 should continue to exibit "stay up for a while after
using application exits" behavior but should exit *immediately* when mike logs
out (before PAM calls pam_close_session).  This should release all of the open
files in /home/mike and it should immediately be possible to unmount /home/mike.

Additional info:

Pam_mount is a PAM module that mounts/unounts volumes (encrypted, samba, Novell,
etc.) at login/logout time.
