[Related question from my side:] Would you be willing to provide debian package generation rules for Xenomai? Something that would spit out .deb files when calling, say, "make deb KERNEL=linux-2.6.x.tar.bz2 CONFIG=my-kernel-config" in a configured userland build directory? That way we could automatise binary package generation for kernel, user libs, development headers, and documentation. And that would allow us to finally distribute them for generic targets like x86 and x86_64 along with the usual tar files. I think such a feature (maybe later enhanceable by RPM) would both be interesting for replicable custom installations as well as for a reference kernel distribution to provide a Xenomai quick-start. > > The problem - prepare-kernel.sh creates symlinks to assorted files in the > Xenomai source tree.
