FYI If you remove the context from the ID of this module, there's gonna be a problem because this module is currently included in both network boot and boot disk assemblies.

[Lennonka]

This context is currently in use in a module in this assembly.

[Lennonka]

For the reasons above, I advise against this change at the present time.

There are further improvements planned for the Provisioning guide. Perhaps de-duplicating usage of the aforementioned module could be part of them. (Let's file a new issue?) cc @jafiala

Afterwards we can consider removing the child context in these assemblies.

Thanks Lena, I agree that we need to fix the other "issue" first. -> Converted to draft for now.
