I know - of course I know that! :-)
Perhaps I don't _want_ (or need) to set up a dns server. And often
I will have to (err, do have to) deal with situations where dns is
unavailable because I am, for example, getting into a remote server
from the dialups ("back end") and not from the usual WAN gateway
link (which might be down).
The only way to ssh into these boxes is if the source box can be
resolved in the dns. I can configure this differently, but I don't
particularly want to.
I'm full of other examples where I *NEED* /etc/hosts to work like I
want.

So have I (on all the remote servers, over 40 of them), but that's
not the point.

Yes, things like that.

No, not really. Well, sort of. Each of these remote sites has a
lan and dialup services. Each site has a wan connection, eg, isdn
or frame relay.

portmap and nfsd have no problems, but the mountd daemon barfs if it
can't do a DNS reverse lookup on the client asking for the
directory. Same with sshd/sshd2.
