We don't even have dosemu packaged. Haven't since RHL 7.1 power tools,
if brew is to be believed, certainly never in Fedora.
Ah, it's in rpmfusion, not Fedora.
I have occasionally appreciated the ability to compare vm86 to
x86emu
when debugging vesa failures, but that's rapidly ceasing to be a thing
I need to care about. I do wonder why its something that needs to be
removed entirely instead of locked in a disused filing cabinet in the
basement, but I'm not going to shed any tears if it goes away.
It may not end up going away. I want to mark it BROKEN, which means
that basically everyone's config will disable it. The problem is that
it's buggy and probably full of security holes.
