Otherwise, newly created users and groups within the CT won't be able to own files. '''Note this is not required for ploop layout, in which quotaugidlimit is enabled with any non-zero value.'''

	Rather than checking these values from time to time by hand, you can use the shell script from below to automatically set the quotaugidlimit based on the needs of the individual containers. Just setup a cronjob for it.
