As the number of things that look for vmlinuz scrolled up the screen,
I lost more and more interest in pursueing this. The amount of churn
we'd have to do to various packages doesn't really pay off vs the number
of people who ask for this. (I think this is literally the 3rd time I've
seen it requested in the 5 years I've been maintaining the kernel)
I'm leaning towards ->WONTFIX
