Yes! Have you found an answer or given up on this experiment? Ive found that even though I edit the /etc/resolv.conf (because the UI won't do it either), the DNS settings disappear on reboot. In our case the primary DNS server is replaced by the FQDN of our AD domain and the secondary is blank.
Basic stuff like this (and the laundry list of bugs in the latest release notes) is making me think this appliance is not ready for prime time.. and I so wanted it to be.
