CGROUPFS-MOUNT(8)           System Manager's Manual          CGROUPFS-MOUNT(8)

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 classi-
       fication of tasks into cgroups.  They are also very intentionally light
       on  configurability  (to the point of non-existence) to keep the imple-
       mentation simple and less error-prone.
