Hello,
Based on my many years of lurking on linux kernel development lists, IMHO,
that is never going to happen. You need the full support of the linux kernel
development community to succeed with your goal. You need to be talking to
the linux kernel development community. You are on the wrong list.

Folks who are truly linux kernel experts have no problem with embedded development
environments. In my experience, linux server environments are orders of magnitude
more complex than embedded environments. True linux kernel experts don't even use
debuggers.

Of course I wish you well with your efforts. But you need to fully grasp the ethos
of the linux kernel development community, before you can succeed at such a goal.

enjoy,
Karen
