Right, not strictly needed, only for consistency, so the language should
be softened, I agree.

That is needed, but the steps that required editing files aren't easily
captured in a transcript, so I didn't capture those, but they are still
required.  I should have added a <do editing step xxx from the doc here>
to make that clear, though I did mention that other than the
kernel .bbappend, the steps I went through were pretty much as
described.  Anyway, hopefully we can get the changes from this thread in
the doc and it will then all fit together.

Right, I missed that step.  It still builds, though there would be
problems with X at runtime due to this.

Yes, necessary, again, I didn't add the notes about editing.
