I understand that the headers in /usr/include/linux shouldn't be overwritten by new kernel installs. But can someone elaborate on Linus's original admonition (http://kernelnotes.org/lnxlists/linux-kernel/lk_0007_04/msg00881.html)? Am I never, ever, ever allowed to update my system headers for the rest of my life, or is it only if I follow some particular procedure, such as recompiling glibc? The reason I want to upgrade my system headers is that framebuffer development requires linux/fb.h to be included from userland (I see no way around that). The version of fb.h in my system headers is 2.2.5, the distro version I originally installed. I'm running 2.2.17 kernel now, which has much newer fb.h which I need. chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
