There are two ways that busybox may be configured -
One (which does not require sym-links) does require that /proc be mounted.
The other configuration choice does require links (either symbolic or hard) but will work without /proc mounted.
This configuration option also allows you to just replace a bb link with an executable and you will get the real-executable. Also a real-executable "wins" according to the usual path rules over the bb link.
From your post, the BBs that you write about must be configured per the first choice above.
I always option my builds of BB according to the second way.
