I personally am already making use of security contexts starting at 2, and
so I'd hate to see us forced to use > 1000, whether we want quota support
or not. Ultimately I'd like a way to be found whereby the security context
range is not directly tied to the quotas, but I realize there are only so
many tradeoffs which can be made to keep the code clean.

Thank you for all of your work on this!

Btw, for those who want to play with special context (assigned by hand), I
change the kernel so on-the-fly security context are allocated from 1000
and up
making sure the one you have select by hand will only be used by this

My idea about vserver quota was a little like that. Some uid remapping.

I was adding another tricks. The quota of all users in a vserver was summed
enter as a special user. Each vserver would be associated with a special
users. For
example, if vserver foo is created, then user quota_foo would be created
it would be possible to limit globally a vserver just by limiting user
