this would work only if /etc and $queue_directory are on the same
filesystem, which is a _very_ _bad_ idea (not only from a security
perspective)

>ln -s $queue_directory/etc/resolv.conf /etc/resolv.conf
this works, but if the purpose of chroot is removing the possibility for
an attacker to make system wide changes, i would not make
$queue_directory/etc/resolv.conf a system file.

what's wrong with copying the file? is it changed that often?
