However, the Intel wireless drivers used to not work when built-in (fixed now, but I still had a legacy config), so my laptop had modules enabled, and MODVERSIONS set. And I don't build initrd's etc crap, very much on purpose. I want to replace the kernel, nothing else, so my /etc/grub.conf file just replaces the distro kernel with my own, and keeps everything else untouched. > I don't think relying on modversions is the complete answer here. Perhaps > we should make modules_install blow away old modules? Wouldn't help one whit, and is against my rules anyway. See above. I want my own kernel, no other changes. That means that I run the distro initrd, which has its modules for bringing stuff up with distro kernels. And quite frankly, when I finally figured out what was going on, I was like *WHAT THE HELL*. That kernel/module.c code was absolute and utter crap in accepting modules that neither matched the kernel version signature (because it had CONFIG_MODVERSIONS) *nor* the actual versioned symbols (because the distro modules had been built without CONFIG_MODVERSIONS). So no, I'm not at all interested in blowing away old modules. I'm interested in having a module loader that isn't complete and utter crap and bypasses all the sanity checks that it has. Which is what that changeset basically does. People can still set CONFIG_MODULE_LOAD_FORCE, but quite frankly, I suspect that anybody who does that is just insane and/or works with proprietary and broken modules. So it's off by default, and hopefully no distro will ever set it.
