cgrulesengd – control group rules daemon Synopsis cgrulesengd [options] Description cgrulesengd is a daemon, which distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group. The list of rules is read…
cgroupfs-mount, cgroupfs-umount – set up cgroupfs mount hierarchies Synopsis Control groups are a kernel mechanism for tracking and imposing limits on resource usage on groups of tasks. These scripts mount and unmount the hierarchies for managing them. cgroupfs-mount cgroupfs-umount Description The location for the mounts these scripts create is /sys/fs/cgroup, which is widely regarded as…
