We'd actually been talking about replacing the current "root=", "extra="

kernel commandline - in the same way that a normal bootloader might.


I think that's a good idea, because that was the next question I
wanted to ask: what's the difference between the root variable (which
in all examples not only contains the root, but alo the additional
argument "ro") and extra, and why should I not  just add more
arguments to the root variable and leave the extra arg empty?

As I understand it now, theres no big semantic difference between
both, and they get actually "glued together" and handed over to the
guest kernel at domain creation time.

Does this answer your question satisfactorily?


Yes, thanks a lot!

Henning
