    As the time passes, the kernel evolves and new ioctls appear. But it's still
    a good idea to compile programs for older kernels (e.g., for stable ones)
    without having to override which ioctls/sockopts/whatever are supported
    by the target system. So it would be better to separate the kernel includes
    from glibc includes and release them as a separate package and just choose
    the right one when compiling stuff.

    Have a nice fortnight
