[ConsoleKit] consolekit userid session counters

[Martin Vogt]

Hello list,

is there a mechanism in consolekit which counts the number
of session for a user?

I like to run an action if the "user_sessioncounter" reaches zero.

Example:

I added to ssh:

>session  optional       pam_ck_connector.so

and if a user logs into the machine:

>if test "$reason" = "session_added"; then
>        if [ -c /dev/nvidiactl ] ; then
>          setfacl -m u:${CK_SESSION_USER_UID}:rw /dev/nvidia*
>        fi
>else
>        if [ -c /dev/nvidiactl ] ; then
>           setfacl -x u:${CK_SESSION_USER_UID} /dev/nvidia*
>        fi
>fi


I'm adding him to the nvidia device.
(this is for this project: http://www.virtualgl.org/)

But if the users login twice and then logouts
from one session all the permissions are revoked. :(

An environment variable like

${CK_SESSION_COUNTER_FOR_USER_UID}

would be helpful here.

Is there such a mechanism?

regards,

Martin
