So, NetworkManager is one of the few packages remaining in Gentopia, and it requires a patch to dhcp, which Uberlord is looking into adding it to Portage, so that is a good thing. On the down side though, something has recently started causing, whenever NetworkManager attempts to get a dhcp address, for it to take longer than 45 seconds to receive a dhcp response. This of course, causes it to fail, and you then get stuck with an apipa address and no networking. Still trying to hunt down the cause. Will keep you posted.
