# Mountpoints of "cgroup" file system
CRIU manages them.
== CGroups tasks live in ==
Starting from version 1. 3- rc1 CRIU saves the information about CGroups each task lives in in the <code>core</code> image's <code>tc.cg_set</code> field. This is an ID of a "set" found in the <code>cgroup.img</code>'s <code>sets </code> section.
Set contains per-controller paths to groups. If a task changes at least one controller's path it is considered to live in different set.
While dumping CRIU gets the set in which the root task lives . Any new set found later should contain only subdirs of the root's set.
