All xenomai releases in a same branch (2.6.1, 2.6.2, 2.6.3, etc...) are 
ABI compatible, it means that Xenomai can be upgraded without even 
recompiling applications using it. Would not it make sense then, to 
package these releases for Debian stable? Using debian backports for 
instance? Or debian "volatile", if it still exists?

Since Leopold is talking about generating patched linux images, does it 
really matter if they do not use the same versions as the ones used by 
Debian?
