Create an informative issue (See each section, incomplete templates/issues won't be triaged)
Using the current documentation as a model, please complete the issue template.
Note: Doc team updates the current version and the two previous versions (n-2). For earlier versions, we will address only high-priority, customer-reported issues for releases in support.
Prerequisite: Start with what we have
After an issue in one of our partners lab: day 2 adding extra workers was not working. The reason: during day-2 operations they have to do some tweaks on network configuration (MCO and Workers). So, new workers try to be installed using only this small config. Which is not enough to complete a network configuration. Instead of using the network configuration from the discovery phase (and --copy-network).
Solution: RHCOS allows a kernel param that will merge both configs. So, the MCO will be happy, it sees his part of config. And it is propagated also the needed network config from the discovery phase.

I have done an small summary/doc: https://github.com/jgato/jgato/blob/main/random_docs/force-networking-configuration-AI.md
In this summary I have observed that this RHCOS kernel argument, can be injected from the AI with InstallerArgs. So, no implementation is needed. Only, to document it.
