Im sorry herbert, it wasnt my intention to catalog your code as unsecure
hehehe...
I only said that because i read somewhere that it was unstable and
(probably?) unsafe.
I thought i read that on your site! :oP
Either way, my apologies.

to cut it short: the problematic issue is the quota storage
(or quota files, which are written by the kernel and maintained
by the userspace tools) except from this, the per context quota
patches provide everything 'real' quota does plus an additional
quota type for the entire context ...

they are unofficial because Jacques doesn't like them, and
they are development because I got almost no feedback at all ...
but they are neither unsecure nor unstable (breaking apart ;)
although I have to admit, that they are currently out of date.

It depends, what you mean by *real* quota ... have a look
at http://www.13thfloor.at/VServer/Concepts.shtml and
tell me what remains *unreal* for you ...
best,
Herbert
