However, there is no need to actually use the configured hostname for
this purpose.  `temp-4224.lcs.mit.edu' is just that, temporary -- I
want my machine to know what its *real* identity is.

From my perspective, when I'm installing a FreeBSD machine, the DHCP
client option serves only to quick-start the installation -- the
machine will eventually have a real address.  It would be useful to me
if sysinstall paid attention to the hostname I specified

You have your mail server set to ``authenticate'' based on the HELO?
That's the only thing in the SMTP protocol that the kernel's hostname
setting has any impact on.
