Sorry, I didn't spot it was part of your quote because of gene in
the second line. Using RedHat might explain the localhost.localdomain,
but not the addition of .com. AIUI RedHat's addition of
localhost.localdomain was the main reason that Debian inserted
it, only to remove it again. I think localhost, on its own,
has been recommended for years. RFC 1912 dates from 1996.
Following the addition, there was a discussion on devel,
which I understood to conclude with the sentiments in
https://lists.debian.org/debian-devel/2005/10/msg00572.html
and its removal.

A little OTT, but if that's the case, then all the more reason to read
RFC 1178 *before* you name the machine at all, and never change it.
Of course, you can always rotate that to 8117 if you're intensely private.
Cheers,
David.
