Description of problem:
Trying to set a static IP address in ingnition config requires a restart of the machine to apply it.
As per Stephen Lowrie:
The flow should be that networking is brought up inside of the initramfs and the kcmdline args apply, ignition runs and applies down the requested config for the real root, the network is brought down, it pivots from the initramfs to the real root, networking is brought up using the configuration that ignition applied
Version-Release number of selected component (if applicable):
Everytime. Apply a file for ifcfg-eth0. The network will be configured after a reboot.
Steps to Reproduce:
1. Create ifcfg-eth0 in ignition config.
2. Attempt to use that IP.
1. DHCP address is the only response.
Static IP assigned.
https://jira.coreos.com/browse/RHCOS-148 doesn't appear to exist. I was going to comment over there, but Ignition isn't responsible for bringing up the network so it shouldn't be responsible for taking it down either. That will need to be done by the adjacent processes in the initramfs. Subtle, but important distinction.

Sorry Alex, that one was deleted because it was a duplicate card. You can comment in the future on https://jira.coreos.com/browse/RHCOS-111
