Fair enough; I'm just going to (slowly) poke at improving the results
on FreeBSD, independent of release schedules.

Yeah, I'm not completely sure either; in my tree I switched root to be $ROOTGRP
https://github.com/emaste/toybox/commit/a576ccc4d035358bce0e40e37a7b4583e2c0d468
so that part could be committed upstream and I can carry a tiny local
patch to set ROOTGRP=wheel instead.
