Re: Linus's include file strategy redux

Lets try another scenario (from user point of view)
Ship kernel sources split in kernel-headers-2.2.18(tar.bz2,rpm,deb) and
kernel-source-2.2.18, and a binary kernel-2.2.18

One user not doing kernel compiles, but with various installed
kernels to try has:
/usr/include/kernel-2.2.18
/usr/include/kernel-2.4.0
/usr/include/kernel -> kernel-2.2.18 (setup at boot-init scripts
                                      with uname -r)
User can compile userspace apps and test kernel modules including
/usr/include/kernel. If glibc is kernel independent, glibc headers
just include 'kernel'. If it is kernel dependent, include
'kernel-x.y.z'.

User rebuilding kernel: kernel-source-x.y.z always look at
/usr/include/kernel-x.y.z, not just kernel.
A developer building a patched kernel that does not change headers
can manually do
/usr/include/kernel-2.2.18-my-pre -> /usr/include/kernel-2.2.18
If he need to change headers, dup include tree.
