.SH NAME

.SH 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.

.B cgroupfs-umount
.SH DESCRIPTION
The location for the mounts these scripts create is
.IR /sys/fs/cgroup ,
which is widely regarded as "the place" for these to be mounted (for example,
.BR systemd
mounts them here as well).
.SH "RETURN VALUE"
Zero for success or if it is determined that we can or should not mount, due to user entries in
.IR /etc/fstab
or pre-existing mounts.
Non-zero for explicit failures.
.SH "CAVEATS & DIAGNOSTICS"
It is critically important for the proper operation of these scripts that you do not manually include any cgroup mount points in
.IR /etc/fstab .
After commenting out any extraneous cgroup entries in
.IR /etc/fstab ,
you should either reboot or manually
.BR umount
them and then run
.BR cgroupfs-mount
again.
.SH 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.
