Libcgroup integration into Fedora ================================= Apart from standard libcgroup features, Fedora adds support for starting system services in given control group(s). If a service init script 1) uses daemon() function from /etc/init.d/functions to start the service 2) and uses /etc/sysconfig/<service name> for its configuration, you can add CGROUP_DAEMON="<space separated list of groups>" to the /etc/sysconfig/<service name> to start the service in given group. Example ------- How to start Apache web server in group cpu,cpuacct:/daemons/http: 1. Configure your group in /etc/cgconfig.conf (see cgconfig.conf man page). 2. Add following line to /etc/sysconfig/httpd: CGROUP_DAEMON="cpu,cpuacct:/daemons/http" During next boot (or after restart of cgconfig and httpd services), your http daemon and all its children should be started in the given groups. Details ------- The daemon() function in /etc/init.d/functions was modified to start the daemon in control group(s) specified by CGROUP_DAEMON environment variable. Therefore it won't work on all services, but only those which satisfy the two aforementioned conditions. CGROUP_DAEMON can contain more than one control group, separate them with space then: CGROUP_DAEMON="cpu:/daemons/http cpuacct:/daemons"
