dhcpcd-3.1 now ships with zeroconf support. I don't think this should be enabled by default as it changes prior behaviour, for instance, breaking failovers. See http://forums.gentoo.org/viewtopic-t-594062.html for the problems this can cause. Please supply a USE flag to control this or at least a warning in the ebuild. PLEASE DO NOT MARK AS DUPE WITHOUT DUE CONSIDERATION. I was asked by the main baselayout dev to submit this bug, and my previous one. Reproducible: Always Steps to Reproduce: 1. In /etc/conf.d/net : config_eth0=( "dhcp" ) fallback_wan=( "192.168.0.2/24" ) fallback_route_wan=( "default via 192.168.0.1" ) 2. Disconnect network cable from eth0 3. /etc/init.d/net.eth0 restart Actual Results: dhcpcd does not return error, preventing the failover from working. Instead it sets the interface to a random address in the 169.x.y.z range. When the option: dhcpcd_eth0="-L" is present in /etc/conf.d/net, failovers behave as they did with dhcpcd 2.x. Expected Results: I expected the failovers to work as they did with dhcpcd 2.x, since no notice was given of the changed behavior.

To be fair, you should be using netplug or ifplugd to manage your network cable being in or out :) I've added a zeroconf USE flag to the 3.1.6-r1 ebuild which controls this behaviour now, with a nice warning as well.
