Why should you screw up the modules you've compiled? They all belong to 2.6 series. > Being modular has nothing to do with the "problem" (except it's probably > required, but Linux _is_ modular for some time now). It gives more freedom to change the implementation resulting in a easy mantainance. Modularity make things easy... little things that work, isn't it a unix motto? :) > Not "can". You have to.

You are talking about porting a SPARC kernel on a 386! I'm talking about having the same binary kernel distribution for your achitecture, let's say i586, and being able to upgrade the kernel without hassles. No person on earth can imagine using a kernel for x86_64 on a i486! :) > You can have it in /boot. In fact, it's not a kernel issue.

Anyway, /boot will always exist as /lib, and you can always do a rm -rf /boot/kernel/modules :) -- Sensei
