When we tried to install Gentoo 1.4rc3, the LiveCD (3stages) had dhcpcd enabled by default, that is allright off course. The problem is that net-setup should disable dhcpcd when choosing to configure the network manually, otherwise ones configured settings gets overrided by dhcpcd. Reproducible: Didn't try Steps to Reproduce: 1. Use a machine on a network with a dhcp server. 2. Start the LiveCD. 3. Use net-setup to configure your ip-address manually 4. Wait a while Actual Results: dhcpcd still running, network config changed by it. Expected Results: dhcpcd stopped, network config kept.
the latest cd has a nodhcp boot option, i will also look at disabling dhcpcd when the net-setup prog is started.
This bug is actually still active with LiveCD install-amd64-minimal-20141204.iso (tested under virtualbox with a Bridged Adapter setting and no dhcp servers on the network) A. When not using nodhcp boot option then, dhcpcd is already running (pgrep dhcpcd) and /var/run/dhcpcd.pid file is intact pointing to the right pid, however /etc/init.d/dhcpcd stop says: * WARNING: dhcpcd is already stopped Using net-setup (as per the instructions here https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Networking#Default:_Using_net-setup ) won't stop the already running dhcpcd and what this means is that net-setup will fail to rewrite /etc/resolv.conf because dhcpcd will keep its own version of that file (in my case empty, so no DNS for me even after the proper net-setup configuration). Solution for this is to pkill dhcpcd before running net-setup. B. When using nodhcp boot option then, even though dhcpcd is already running as per this bug: https://bugs.gentoo.org/show_bug.cgi?id=316817 you can still stop it via: /etc/init.d/dhcpcd stop and now net-setup will work fine (with regards to DNS).
