With Ignition v2.5.0 Ignition-Dracut will be merged into Ignition itself.
Per [1] it was decided to move the CoreOS specific bits over here in this repo.

This includes a transitional hack (yes its an ugly, terrible, no-good hack) but the hack is intended to be short term until the 2.5.0 Ignition lands. Once 2.5.0 lands dracut/31ignition can be burned.

Ugh @jlebon looks like my local testing was flawed. I'm not sure we can remove 30ignition/<stuff> since it breaks the build. The Ignition package puts Ignition in /usr/lib/dracut/modules.d/30ignition/ignition. So we can't just delete the dracut modules from the Ignition package unless we put the ignition binary in the source tree.

I was not able to find documentation about providing in-tree overrides.

Ugh @jlebon looks like my local testing was flawed. I'm not sure we can remove 30ignition/ since it breaks the build. The Ignition package puts Ignition in /usr/lib/dracut/modules.d/30ignition/ignition. So we can't just delete the dracut modules from the Ignition package unless we put the ignition binary in the source tree.

So here's an idea that was discussed this morning:

  • in the Ignition PR, rename the dracut module to e.g. ignition-v3
  • in our module-setup.sh here, we do something like:
if dracut_module_included "ignition"; then
	exit 0
fi

so that it's a no-op if we're on the old Ignition.

  • we merge this PR
  • we merge the Ignition PR
  • release new Ignition
  • bump Ignition in FCOS
  • at some point later on, we can drop the module-setup.sh hack, and rename back the module in Ignition to ignition.

The advantage of this is that in the Ignition PR, we get to test the final state in CI before merging and cutting a release.

The PR's CI will have to also sed this line to --add=ignition-v3.

As discussed in IRC, the mechanics of getting everything in place before the 2.5.0 release is more risky than just cutting over. Once 2.5.0 lands, this will be ready.

Pending 2.5.0 release an RPM build.

LGTM generally. Some nits, including a couple things that came over verbatim from ignition-dracut.

CI is failing because of the file conflicts. Want to include the Ignition override as part of this PR? See #522 for an example.

Needs one last fix, and then I think this is good to go!
