  3. .SH NAME
  4. cgroupfs-mount, cgroupfs-umount \- set up cgroupfs mount hierarchies
  5. .SH SYNOPSIS
  6. Control groups are a kernel mechanism for tracking and imposing limits on resource usage on groups of tasks.
  7. These scripts mount and unmount the hierarchies for managing them.
  8. .PP
  9. .B cgroupfs-mount
  10. .LP
  11. .B cgroupfs-umount
  12. .SH DESCRIPTION
  13. The location for the mounts these scripts create is
  14. .IR /sys/fs/cgroup ,
  15. which is widely regarded as "the place" for these to be mounted (for example,
  16. .BR systemd
  17. mounts them here as well).
  18. .SH "RETURN VALUE"
  19. Zero for success or if it is determined that we can or should not mount, due to user entries in
  20. .IR /etc/fstab
  21. or pre-existing mounts.
  22. Non-zero for explicit failures.
  23. .SH "CAVEATS & DIAGNOSTICS"
  24. It is critically important for the proper operation of these scripts that you do not manually include any cgroup mount points in
  25. .IR /etc/fstab .
  26. After commenting out any extraneous cgroup entries in
  27. .IR /etc/fstab ,
  28. you should either reboot or manually
  29. .BR umount
  30. them and then run
  31. .BR cgroupfs-mount
  32. again.
  33. .SH RESTRICTIONS
  34. These scripts intentionally do not do any cgroup management or classification of tasks into cgroups.
  35. They are also very intentionally light on configurability (to the point of non-existence) to keep the implementation simple and less error-prone.

  37. Serge Hallyn and Tianon Gravi
  38. .SH HISTORY

  40. .BR cgroup-lite
