+WARNING: Because of existing issues in the Linux kernel's freezer

 Using quotas inside containers
 ------------------------------
 
+Quotas allow to set limits inside a container for the amount of disk space
+that each user can use.
 This only works on ext4 image based storage types and currently does not work
 with unprivileged containers.
