I'm circling all the way back to the beginning on this problem.  I was
looking into whether we could easily fix /bin/sh or whether we should
just warn that you can't bootstrap from systems earlier than 8.4.

What I discovered along the way is that /bin/sh isn't a build tool and
thus isn't a blocker to bootstrapping from 8.2.  That is, the build
system doesn't first build a newer sh, then use it for the rest of the
build.  You created the /bin/sh problem by running a 10.1 world in a
chroot on an 8.2 kernel.  I overlooked that fact when I first read this.

So the real question would be why you failed to build a 10.1 kernel on
an 8.2 machine, and there is no detail in your original report about how
or why that happened.
