I thought the idea was to offload the process to the user's computer
(because that's the best place to ascertain version) and not necessarily
the user. It would rather be like NVIDIA's display driver installation
file. The user doesn't even know he/she's compiling (well, they're made
aware but they don't have to know how).

I just thought I'd point out that that in subsequent discussion, just be
sure to mention that what this really boils down to is a conflict
between what certain spinners and users want (the capability to slim
down their distro to just the bare essentials ... they call it
optimizing) and what maintainers and developers want (easier code
maintenance, no need to write the smart applications that alleviate all
the thinking from the users' part).

But even if you do go on and scrap DKMS and kernel modules from being
separate packages in Fedora, I hope that Fedora helps come up with a
standard for packaging kernel modules in external repos. Fedora is the
best body to regulate the chaos that's going on out there.

My own personal opinion is that a look at ATRPMS' kmdl2 and blessing it
as a standard is the correct thing, speaking of the technical side.
Either that or completely stop relying on putting meta-info into blasted
RPM filenames. :)
