initrd: can't disable NICs during boot
If I have two NICs and I want one to come up and the other one to not attempt any network bringup in the past I specified something like:
rd.neednet=1ip=192.168.122.111::192.168.122.1:255.255.255.0:initrdhost:ens2:none:192.168.122.1ip=ens3:off
However this doesn't work as expected now. The system has to timeout the ens3 connection in the initramfs before it comes up.
