but chroot is still buggy (even if it's running under a vserver) so that
one could break out of a chroot jail and get to other services on the
same vserver?

ok. I'm kinda sad, that this means one can't use standard rpm's.. cause
I'm gonna setup these systems in small shops, where they don't have the
knowledge/expertise to compile themselves, and therefore standard
distribution rpm compatability would be great to have..

I guess, I'm gonna have to think of something.. :-(

Then I will have install the services on the costumer machines, without
vserver (unless they explicitly want it with its advantages and
this would mean that I have to copy config files over ONLY.. from the
vserver to the costumer server - whereas otherwise I would be able to
just copy the vserver directory :-(

and then I would have to maintain a secured base linux system, for the
costumer server. I'm just gonna use my vserver box's root server for

Well it seems the path is becoming more clear to me now :-)

it's difficult to make a standard installation, that doesn't remove
flexibility and ease of use and doesn't compromise security either.

P.S. I've sent this mail to the vserver-mailinglist also, so that others
might gain from our discussion :-)
