What I neglected to realize when you made the LVM suggestion,
is that by creating unique partitions for each vserver, setting up
quotas for each discrete vserver would be simple by initializing
quotas on the main server.

Each vserver LVM partition /vserver/tst1 for example, would contain
a unique quota.user file and it would not matter that a UID of
the same enumeration had a quota set on another vserver or
the primary filesystem as quotas are relevent only to the current
partition and quota.user file (in thise case /vserver/tst1/quota.user).

The vserver would still have control over it's own quotas as the
file is rw root in the directory of "/" within it's chroot. And the
server running in security context 0 would do the actual enforcement
and maintinence such as quotacheck.

Did I miss anything?
