Some packages (Not modules) depend on the kernel's source, so it might be better to rebuild those packages after a kernel upgrade, but currently those packages are just in the @world set and can't be distinguished. For example, how about rebuilding those packages when running: emerge @kernel-dependents
Which for example?
Doesn't portage check for the kernel for some packages before compiling them? Such as media-libs/mesa for example.
In normal cases, you should not need to rebuild those user-space packages. Linus is very much against user-space breaking changes to system calls. The methods employed include creating new syscalls or utilizing an existing parameter (w.g. bit flag) to add functionality. Both of which are done to prevent breaking user-space apps. If newer apps require newer kernels, that's a dependency that will be addressed by the upstream application and the package maintainer in concert. Am I missing the point of this bug?

I see, so the kernel has never seen major changes to system calls since a long time? And probably shouldn't anytime soon? Well whatever you guys see suitable, I have actually set this bug as an "enhancement" (Not something severe), but the assignee reset it back to "normal". I just reported this because I always tend to upgrade my kernel before doing a full @world update so that new packages would use the new kernel source. Just precaution I guess.
Ok, I don't really think this makes sense. It's a bit of overkill to rebuild world after a new kernel, but you certainly can continue to do so if you like.
