I assume 'on the system' referrs to the host?

which was almost expected ... the docu is just
outdated, a community member started to update
the quota documentation, but was lost in action ...

the best docu atm can be found at the documentation
section on linux-vserver.org, here is a link to the
quota part:

http://vserver.13thfloor.at/Linux2.6/index.php?page=Per+Context+Quota

basically you have to add a quota hash for each
(part,xid) tuple and use the vroot device to proxy
quotaioctls in a secure way to the kernel ...

HTH,
Herbert

PS: is this linux-vserver in Japan?
