Group quotas are more flexible. They provide consumption control both
per home directory and per-project directory.

According to Redhat's convention - an user is created together with an
unique primary group whose name equals the user's name. Home folder's
space consumtion is regulated using per-group quota on user's primary
group.

Usually, users participate in different projects having corresponding
file-sharing folders in the file system. For each project one creates
a separate group. All users participating in the project are assigned
members of this group. Consumption per project folder is regulated
with per-group quota on the project's group.

One should not, of course, forget to set appropriate group permitions
on the folders and to activate the set-group-id bit.

I read all this 12 years ago in the RedHat's users guide.

Kind regards,
Alexander
