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
