Leveraging system hostname as part of a jail's hostname

[Joseph Ward]

Thanks for the suggestion, but my case is a bit wacky.  I'm actually
creating the jails on a build box, packaging them, and deploying them to
a bunch of different host machines, so ideally the change would be
handled across all machines without any changes.  Fortunately, the
suggestion in the other sub-thread worked well.  (In a previous
iteration I'd had the deploy script make the change on each machine, but
that's a lot less clean than just having a single jail.conf that worked
for all).
