[meeting] Discuss adding systemd-networkd to FCOS

[bgilbert]

Placeholder meeting issue for coreos/fedora-coreos-config#574. I'm locking this issue; please continue discussion in the linked PR.

[dustymabe]

We discussed this during the community meeting today.

The two options that were discussed were:

• A. Ship networkd in the base layer. Stop removing the binary files during compose.
  • Also disable it by default using a systemd dropin and write documentation on how to enable it, along with accompanying documentation on the possible things that might not work as a result of enabling it.
• B. Break out networkd into its own subpackage (if upstream systemd will accept the split) so it can be package layered easily.
  • Add a FAQ entry about using networkd.

There was lots of great discussion and creative ideas on how to solve the problem and the implications of both options. For now we have settled on:

13:35:07 dustymabe | #agreed we'll reach out to the systemd team to see how they
                   | feel about making a systemd-networkd subpackage. If they
                   | refuse or are not interested we will explore option A
                   | (including systemd-networkd in the base layer) but with a
                   | dropin that disables it by default.

The next step here is to reach out to the systemd team about the package split and base our future work on the outcome of that discussion.

I will cross post this in coreos/fedora-coreos-config#574 where the targeted discussion for this has been happening.

As part of the Fedora 33 rebase users will be able to package layer the systemd-networkd rpm on top of Fedora CoreOS because the package was split into a subpackage for Fedora 33. This work landed in the next stream in 33.20201006.1.0:

The package was broken out and is now able to be layered.

The fix for this went into testing stream release 33.20201116.2.0. Please try out the new release and report issues.
