Reason
======
$ md5sum /etc/services  /srv/chroot/sid/etc/services 
40cb541e1c5419af213cd4fd78487487  /etc/services
cdd36c264083b124f2bb48415f3acab1  /srv/chroot/sid/etc/services

=> file from netbase&host not equal to the one in chroot

Explanation
-----------
<jcristau> ah right
<jcristau> because schroot iterates around getservent, it doesn't just
copy the file

Solution
========
Copy the files instead?
