polyinstation and removable media

[Stefan Schulze Frielinghaus]

Something strange happens when /tmp and /var/tmp are polyinstantiated
for all of my users except root and adm.

/etc/security/namespace.conf:

/tmp      tmpfs          tmpfs      root,adm
/var/tmp  tmpfs          tmpfs      root,adm

When the user logs into a GDM session using GNOME and plugs in a
USB-Stick, DVD or whatever the device is _not_ mounted. Everything else
works fine. The directory in /media is created and everything is setup
correctly but the final mount command is not issued.

The logfiles don't speak that much but maybe this is a little hint.

Jun 21 19:20:19 test kernel: sd 0:0:0:0: [sda] Attached SCSI removable
disk
Jun 21 19:20:19 test console-kit-daemon[1629]: WARNING: Couldn't
read /proc/2766/environ: Error reading file '/proc/2766/environ': No

Jun 21 19:20:20 test gnome-keyring-daemon[2647]: adding removable
location: volume_uuid_47DB_BAD8 at /media/blub

And here is a logfile without polyinstantiation:

Jun 21 19:25:00 test kernel: sd 1:0:0:0: [sda] Attached SCSI removable
disk
Jun 21 19:25:00 test kernel: sd 1:0:0:0: Attached scsi generic sg0 type
0
Jun 21 19:25:01 test gnome-keyring-daemon[3746]: adding removable
location: volume_uuid_47DB_BAD8 at /media/blub
Jun 21 19:25:01 test hald: mounted /dev/sda1 on behalf of uid 500

Both logs say that the media was mounted but that's not true if
polyinstantiated. Maybe something related to the console-kit-daemon
warning message?

Does someone has an idea or can confirm this?

Best regards
Stefan
