After drivers probe, barebox invokes init to source init scripts and do the countdown and such. This is written in C, but you can override it with an /env/bin/init shell script, which is what you did here. I would not recommend this. Drop /env/bin/init and use the same C init nearly everyone else does. You can still customize it via the /env/init/ scripts > Is there a recommended way to go about this?

Patches to the mailing list are the usual way of contributing.
