Recently a bug in wa-linux-agent was found, which happened when overriding the SSH public key provided by Ignition configuration during provisioning. It was not a critical bug, because that override happens only under limited circumstances.

A fix PR by @peytonr18 was already merged.

It is still necessary to pull in the fix into flatcar/scripts repo. Since then there is no new release of wa-linux-agent yet, so it is necessary to pick up the fix as a separate patch.

Current wa-linux-agent version of Flatcar is still 2.9.1.1, while upstream has a newer version 2.12.0.4. So in case of main (future Alpha), it might be better to bump the version and apply the patch.

In case of other channels, it would be better to simply apply the patch without updating version.
