Yeah, I can tell you and Michael apart. My point is that our users won't
make the connection between the game ("controls don't work, it is
broken!), the kernel and some udev rules in your joystick package. You
must explicitly tell them to install it and only very few of them file
bug report anyways.

Sure. This is better than nothing but the kernel issues were reported
six years ago. With a bit of good will we could have already mitigated
this for a large number of users.
