No, but it's the same kettle of fish as chroots, jails and vps systems -
basically
there is a need to disable dependencies that provide what the host already
does.
We current have nojail for FreeBSD jails, novps for VServer/OpenVZ systems
and
a few others. I would be trivial to add another no for prefix :)

It compiles and works on Linux/glibc/uclibc, FreeBSD-6 and NetBSD-4.
So it stands a fair chance of working on Darwin for sure.
I have no idea about Solaris, but it should work as it sports libkvm which
we
use to find processes.

If OpenRC compiles and /bin/sh points to a POSIX shell it should work as it
stands.
At present there is no need for the default interpreter to be changed, but
there may
be the need for Prefix.
