NAME

       cgrules.conf - libcgroup configuration file

DESCRIPTION

       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>

       Where:

       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.

EXAMPLES

       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.
