I am writing my own NetworkManager config via ignition into /etc/NetworkManager/system-connections. It works, but only after the second reboot of the system. On the first reboot there is another automagicly appearing NetworkManager config that overrides it in /var/run/NetworkManager/system-connections/.

One theory for this is that this is coming from initramfs on the first boot because the ignition is only applied at the end of the first reboot, and thus it requires a second reboot to actually use the config that was applied in ignition.

[core@localhost ~]$ rpm-ostree status

              GPGSignature: (unsigned)

Here's a log of my encounter with this bug. The NetworkManager log shows before and after the second reboot:

### This is my config using static IP address:
[core@localhost ~]$ sudo cat /etc/NetworkManager/system-connections/ens18.nmconnection
[connection]
id=ens18
uuid=6c84d90c-72bf-438b-865f-f02f11a1b911
type=802-3-ethernet
autoconnect=true

[ipv4]
method=manual
dns=1.0.0.1
dns=1.1.1.1
addresses=10.99.0.3/24
gateway=10.99.0.1

[802-3-ethernet]
mac-address=be:e8:58:c1:85:f8




## This is the one that shows up automatically on the system, ONLY on the first reboot.
## But it's DHCP not the one I assigned statically:
[core@localhost ~]$ sudo cat /var/run/NetworkManager/system-connections/ens18.nmconnection
[connection]
id=ens18
uuid=109c7d0a-3d80-48dc-a3cb-21498c4533cc
type=ethernet
autoconnect=false
interface-name=ens18
permissions=
timestamp=1564353774

[ethernet]
mac-address=BE:E8:58:C1:85:F8
mac-address-blacklist=

[ipv4]
dns-priority=100
dns-search=
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-priority=100
dns-search=
method=link-local



## Here is the network manager log as seen on the first reboot:

## The IP address on first reboot is the one it got from DHCP, not the one I statically assigned :(

### Then after a SECOND reboot it works because the one in /var is gone:

Note that this is a PXE install, so the first boot is the PXE installer and the second boot is the Ignition run. So the DHCP config is propagating from the Ignition run to the real root.

The network setup by Dracut during the first boot ignition bleeds through by leaving the interfaces configured. I'm currently working around this by adding the following to the Ignition config:

storage:
  files:
    - path: /usr/local/bin/purge-dracut-network.sh
      mode: 0755
      contents:
        inline: |
          #!/bin/sh
          [ -d /run/NetworkManager ] && rm -rf /run/NetworkManager
          links=$(ip -j link list | \
              jq  -r '.[] | select(contains({"link_type": "ether"})) | .ifname')
          for link in $links; do ip addr flush dev "$link"; done
systemd:
  units:
    - name: purge-dracut-network.service
      enabled: true
      contents: |
        [Unit]
        Description=Purge dracut generated network
        Before=NetworkManager.service
        [Service]

        ExecStart=/usr/local/bin/purge-dracut-network.sh

@EnigmaCurry @basvdlei - can you try out the latest testing devel image from https://builds.coreos.fedoraproject.org/browser and see if it fixes the problem for you.

@dustymabe this issue is fixed for me. I just tested with version 31.20200325.20.0 and my work-around is no longer necessary. Thanks!

We are now using NetworkManager in the initramfs and also propagating network information from the initramfs (kargs) when appropriate, which we think fixes this issue.

See #394 (comment) and the preceding discussion for more details.
