If programs or other components of the world do have to
be in sync with kernel or system files (sys/*.h), then
I conclude that world also has to be compiled. In this
regards, it means a change of the kernel, and if the
kernel did change, kernel and world are out of sync,
which implies that both have to be compiled.
