Hi guys,

I have a security question, in regards to vserver.

I read this article about chrooting your services
http://www.gnujobs.com/Articles/23/chroot.html
and if you did so, as I understand it - it would be kind of achieving
the same as vserver - from a hackers standpoint - without all the smart
benefits.(no disrespect meant).

In the comments I saw this article about breaking a chroot.
http://www.bpfh.net/simes/computing/chroot-break.html

My question is, if anyone know or have tried wether or not the chroot
functionality of vserver can be broken like this? or does the kernel
changes help ensure, this never happens?

This just to know how well I should sleep at night, with vserver
installed :-)
