You could ask this if all images were indeed equal. However, they're
hierarchical, and there's one that is there when the box starts up, and
can't be gotten rid of. If there weren't a "real" hostname, there would
never be a place in the code where you don't have a better choice than
using thread0's credential.

Quite true. I suspect that most variables replaced by vnet always have
a context that they naturally belong to, and would never need to know
about a "real" value. I think it's the few that are outside of vnet
that would most show this.
My focus right now is jail integration, so these are the parts that I
notice, as vnet wouldn't be integrated with jails so much as placed on
top of them (as they are now placed on top of vimage which is almost but
not quite entirely vnet).
