I just upgraded a Ubuntu 12.04 server to 12.10.
It was built with MAAS but no other servers had been added to its private network yet, but I confirmed that dnsmasq was setup correctly for DHCP and iptables for forwarding, etc... Now I that I have upgraded to 12.10, DHCP is no longer available and I found that dnsmasq was removed. What is controlling DHCP now, and where do I edit the correct configuration. This has to be done before I build the other servers and my small testing cloud.
