I realize that.  What I'm saying is that "rpm -e --nodeps" of a 
package, removes *that one* package.  Telling apt it is ok to 
remove the deps too will remove half of your OS.  That's not what 
someone wants.

Nvidia should have Conflicts: XFree86-Mesa-libGL in their package 
ultimately.  That would tell users they must uninstall Mesa 
first.  Or, they could just not do the bogus file removal 
trickery at all, and rpm will automatically detect file conflict.  
Their installer could detect that automatically, and offer to 
replace the system supplied libGL by uninstalling the 
XFree86-Mesa-libGL package.

That would be the cleanest method IMHO, but I'm not sure how easy 
it would be to convince them to do that.  Their users will have 
unnecessary problems and difficulties though until they make 
their installation process and rpm packaging nicer.  I'd even be 
willing to discuss it with them and offer them advice if I knew 
who to contact there.
