And it's not just the kernel headers that matter but certain of the configuration options you use in the kernel. > I know I need to change the link (I use eselect) when changing > permanently, but I've always done this *after* booting to the new > kernel and making sure all services started properly and everything > is running smoothly. As I use nvidia-drivers, I have to do it before rebooting if I want an X display; therefore I let portage do it by having the symlink USE flag set.
