Xeno's build scheme is going to be refactored as explained here:
https://mail.gna.org/public/xenomai-core/2005-10/msg00089.html

Your proposal seems to complement the solution, since in a way or another, we 
will need to organize the source tree in order to reflect the kernel / user 
split. Going for a strict Debian approach for doing so is another issue; I'm not 
  opposed to it, but that's not a pre-requisite to split the codebase anyway.

I suggest that we restart this discussion after a prototype of a statically 
embeddable Xenomai core into the Linux kernel has been achieved; from that 
point, it should be easier to progress toward the user-space revamping, since we 
will have the complete picture about what is needed, specifically in terms of 
configuration and file dependencies. This task is #1 on my list after 2.0 is 
out, so the topic is going to be revived quickly.
