I'm sad no one reported qemu-monitor break, that one is kind of important. count.out arguments broke it as an init program, since the kernel adds trash parameters to every init. Is anyone using this repo, I wonder? Keep pushing, keep pushing. One day it gets good enough, and the whole world will see.

it, so I'm just going to forward the common options to the old shell script for
