My hassle is usually: Where do I dig up that keyboard and spare HDMI video source to bootstrap the Pi. Currently the MAME cabinet does that well, but not everyone has a MAME cabinet.
But you can’t do that from a raspbian image, and if you want me to mod my file system post install that only works assuming I can mount it (eg I have another Linux box with keyboard).
I’ve had this problem multiple times and find this approach really nice (and wish it shipped with raspbian!)
