Yet there were some issues with that part, so I've sent a small
patch-series to busybox to fix the noclobber stuff:
    http://lists.busybox.net/pipermail/busybox/2017-December/086039.html

So, with this, we should be able to:

  - invert the dependency chain, so thatr busybox now depends on all
    otehr packages that it may install applets of;

  - drop the big list of applets-to-disable in busybox, and rely on the
    install-noclobber install rule

If upstream accepts that series, of course...

Regards,
Yann E. MORIN.
