Ok, i've got things working, ssh by adding it to the tty group and screen
by making it sgid. But, again, i don't think this is the real solution, in
my host a normal user doesn't need to be in the tty group to be able to
ssh, or screen doesn't need the sgid bit set to work in the host.

Btw, when i extract the stages tarballs (i tried a stage2 & stage3) the
rights are as in the vserver. I don't know why (and how) it is
different when compared to the host.

I'm running Gentoo, 2.6.11.6-grsec-vs1.9.5 on an amd64,
