       cgrules.conf - libcgroup configuration file


       cgrules.conf configuration file is used by libcgroups to define control
       groups to which a process belongs.

       The file contains a list of rules which assign to a defined  group/user
       a control group in a subsystem (or control groups in subsystems).

       Rules have two formats:

           <user>                   <controllers>       <destination>
           <user>:<process name>    <controllers>       <destination>


       user can be:
           - a user name
           - a group name with @group syntax
           - the wildcard '*', for any user or group
           - '%', which is equivalent to "ditto" (useful for
             multi-line rules where different cgroups need to be
             specified for various hierarchies for a single user)

       process name is optional and it can be:
           - a process name
           - a full command path of a process

       controllers can be:
           - comma separated controller names (no spaces) or
           - * (for all mounted controllers)

       destination can be:
           - path relative to the controller hierarchy (ex. pgrp1/gid1/uid1)
           - following strings will get expanded

                 %u     username, uid if name resolving fails
                 %U     uid
                 %g     group name, gid if name resolving fails
                 %G     gid
                 %p     process name, pid if name not available
                 %P     pid

                 '\' can be used to escape '%'

       First rule which matches the criteria will be executed.

       Any text starting with '#' is considered as a start of comment line and
       is ignored.


       student         devices         /usergroup/students
       Student's processes in the 'devices' subsystem belong  to  the  control
       group /usergroup/students.

       student:cp       devices         /usergroup/students/cp
       When  student  executes  'cp'  command,  the processes in the 'devices'
       subsystem belong to the control group /usergroup/students/cp.

       @admin           *              admingroup/
       Processes started by  anybody  from  admin  group  no  matter  in  what
       subsystem belong to the control group admingroup/.

       peter           cpu             test1/
       %               memory          test2/
       The  first  line  says Peter's task for cpu controller belongs to test1
       control group. The second one says Peter's tasks for memory  controller
       belong to test2/ control group.

       *               *               default/
       All  processes  in  any subsystem belong to the control group default/.
       Since the earliest matched rule is applied, it makes sense to have this
       line at the end of the list. It will put a task which was not mentioned
       in the previous rules to default/ control group.
