1) The top posting in this thread is nigh unbearable, please bottom post
in order to keep the flow of conversation.

2) The busybox config fragments was added in this cycle, which is
probably the reason for no official documentation yet.

3) There is an example in the bug report where it was added
(https://bugzilla.yoctoproject.org/show_bug.cgi?id=3379) which you can
look at if you wish to be an early adopter and test this _new_ feature.

4) For simplicity I have copied the explanation in below:

So, all you need to do is add CONFIG_RFKILL=n or whatever the config
name is and that should remove rfkill from the busybox command set.
