Hmm, in that case I'll actually try to run this program on FreeBSD with root

But, to summarize then chances for generic units are slim. The unportable
garbage "linux" unit is then the only solution, and then hope that cut down
linuxes don't cut it out.

If such a recent Darwin doesn't have it, then IMHO it is not an option now.
