Comment 9 for bug 979720

@#7:Jamie: I added these to my custom rules, to make sure named/dhcp work as expected.
The main problem was that dhcpd was installed and configured, but starting it was denied. The upgrade process wanted to start dhcpd, but since starting was denied it couldn't do it and exhausted an error hindering apt to finish configuration. In tune the upgrade process failed. Changing dhcpd to start at system start temporarily solved the error – but: the upgrade process should not depend on services are enabled to start at system start or being enabled to start at all!
