AFAIK, most machines are configured with matching hostnames, forward and
reverse.  This is necessary to get into a lot of FTP servers, so most users
that do not do mass-installs are likely to get it right.

I wouldn't mind seeing sysinstall ask for a SmarterHost, as that would be
very useful for end users, but claiming there is no point without it does
not match at least my experience.
