True. But I am sure it would be easy for some rpmfusion developer to create a 
custom yum plugin that would check the existence of an appropriate kmod 
package for every new kernel that is to be pulled in on an update, and if the 
kmod is missing, do the yum update exclude=kernel* instead. This plugin could 
be a dependency of kmod-nvidia, and only users who install kmod-nvidia would 
use it.

I am not familiar with coding yum plugins, but I believe this is not too hard 
to do. And there certainly is a lot of demand for this kind of thing from the 
users, apparently.

Nothing specific is asked from Fedora here. The users just want the conditional 
kernel updating to be done automatically rather than manually, so that they 
don't need to learn how to work around the problem when it appears.

If the rpmfusion repo provides the 3rd party software, they could easily 
provide the above custom yum plugin, right? That way the entire thing can be 
made fully automatic and the user need not worry about it. Once the user 
installs the kmod-nvidia package, the nvidia-kernel-yum plugin gets pulled as 
a dependency, installed, enabled, and from then on everything is transparent 
to the user.

We only need to convince someone knowledgeable to write that plugin and 
package it to rpmfusion repo. AFAIK, once this plugin is done, it doesn't even 
need any maintenance or so. Hell, if I had a free week to learn yum a bit, I 
would do it myself. And I don't even use any nvidia cards under Fedora atm...

HTH, :-)
