Carlos, All,

Sorry, I mis-interpreted your comment above, as "user-provided rootfs []
must not do this" to which I appended in my head "but that is exactly
what I want to do in my case."

I'm sorry, I should be more careful in my interpretations in the future.

So, I'll take that as a hint to further improve the section that
explains how filesystems are generated, to more carefully describe and
explain the sequence.

Thanks again for the feedback! :-)

Regards,
Yann E. MORIN.
