Hmm, that tickles my fantasy once again: Could we derive generic .specs
from your files to include them in the Xenomai distribution? Then some
additional Makefile rules could provide a "make rpm" that generates
packages for kernel and userland (when given some kernel.tar.bz2).
Basically, your steps generalised and automated.

This would help us to provide, e.g., an i386 pre-built package with
reasonable default config, something I still consider useful. But, of
course, it must not cost any effort :). Automated rpm generation would
be a big step in that direction.

BTW, have you seen my Xenomai.spec for the SuSE packages I once posted?
Attached is an updated version. It splits the Xenomai userland in
several sub-packages to allow selective installation.

Yeah. Who's going to do this? ;)

[Really, it depends on someone feeling enough need to work on this (or
sponsor the work). A few pieces are already there from previous RTAI
efforts towards x86-64 support. But now it takes a clean implementation
over recent Linux/I-pipe/Xenomai.]
