Don't know if this is the "more" you're looking for....
Short version:
Libc et al are built to talk to kernel using interface spec X.
You build & install latest kernel, with its headers (spec Y).
Reboot to that kernel, and the first app to run into an X vs. Y difference
will barf when a library calls the kernel.
Solution: (other than waiting for a distro upgrade :-)
Build the latest and greatest kernel *with old headers*. If you need
something in the new headers, then you also need to rebuild libc et al. Linus
is advocating the separation of headers and code - headers go in /usr/include
and are matched to /usr/lib. Code (including the kernel) refers to that.
