Is it really not feasible to do a run-time check? It should generally be possible for stable userland to work with the kernel from stable, testing or unstable, as there is otherwise no good way to do upgrades. If not, this incompatibility must be mentioned in the package description.

Why would this matter to applications? Ben. -- Ben Hutchings It is easier to change the specification to fit the program than vice versa.
