cgroupfs-mount, cgroupfs-umount - set up cgroupfs mount hierarchies
Contents
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.
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).
History
This package was originally derived from the cgroup-lite package from Ubuntu.
Name
cgroupfs-mount, cgroupfs-umount - set up cgroupfs mount hierarchies
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.
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.

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.
