# cgroupfs-mount(8)

set up cgroupfs mount hierarchies

## NAME

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 "the place" for these to be mounted (for example, **systemd** mounts them here as well).

## RETURN VALUE

Zero for success or if it is determined that we can or should not mount, due to user entries in */etc/fstab* or pre-existing mounts. Non-zero for explicit failures.

## CAVEATS & DIAGNOSTICS

It is critically important for the proper operation of these scripts that you do not manually include any cgroup mount points in */etc/fstab*. After commenting out any extraneous cgroup entries in */etc/fstab*, you should either reboot or manually **umount** them and then run **cgroupfs-mount** again.

## RESTRICTIONS

These scripts intentionally do not do any cgroup management or classification of tasks into cgroups. They are also very intentionally light on configurability (to the point of non-existence) to keep the implementation simple and less error-prone.
