I have been keeping a running list of busybox/toybox deficiencies and differences. There are more than I would have expected. An alternative is to use crunchgen from NetBSD (also included with some of the later BSDs) which crunches full-featured, source tree versions of multiple utilities in a single, static binary. What busybox refers to as a "multi-call" binary. It will be larger than busybox of course. I get evertyhing I need in a binary less than 5M.
