I don't mean to hijack the thread here, but unification as a way to
help his resource utilization, could someone please point me to a good

I have searched the vserver wiki, but there doesn't really seem to be
anything on how to setup and use unification. Also, does unification
change the upgrade/maintenance process?

Thanks
John
