XFS group and project quotas

XFS supports a quota system, that can handle quotas by user, group, or project. The project quota system is meant for setting quotas on directory hierarchies, e.g. you want to set quotas on users' home directories, but allow them a different quota in some shared directory.

What the documentation and the man page for xfs_quota(8) do not mention is that group quotas and project quotas are mutually exclusive. I.e. if you turn on group quotas on filesystem, you cannot turn on project quotas, and vice versa.

Here are my simple scripts for setting up XFS project quotas to set quotas on users' home directories: https://github.com/prehensilecode/xfs-project-quotas
