Vunify fetches the selection of files to try and unify (hard-link) for
inspecting the package databases.
Sam Vilain did a script to unify files based on inspecting them, I believe
he was using this for unification of Debian vservers in a commercial setup:

How are you going to manage it?

vservers can't access the hosting-server's filesystem or process space
(unless you specifically cause it to happen by say hard-linking a file into
the vserver's space)--that's the idea of these patches.
I don't think these last three points are directly related to vserver. For
example if you are paranoid, you are probably doing remote-syslog/serial
logging and have append-only log files on disk:

That's what `apt-get' is for :-). I think you really need to run the
necessary commands run in each vserver and then re-unify them again
afterwards to pick-up the updated files introduced in the upgrade.

Computers only deal with IP Addresses (numbers). For hosting multiple
websites (different DNS names) on one IP address you will need to turn on
Apache's ``NameVirtualHost'' option.
Details on how to use/configure the Apache webserver are not related with
vserver and can be found on the Apache.org website:

I'm not sure what you're trying to achieve.
Hope that helps,
