I installed turnkey-tomcat 11.2 on Mac Mini 2011 (Lion & Snow) today. I got everything work fine but I did found out the udhcpc has some issue to get ip from my WRT54Gv4 router. I remembered that this issue had been detected in the past. udhcpc is ok with built-in BCM ethernet card but does not work with BCM wifi. I replaced udhcpc with dhcp3-client (dhclient) and it works fine. I strongly recommend that later turnkey release may replace udhcpc with dhclient.
