Well, I agree this seems like a bug. We _do_ have debconf, so surely it
should be used to _get_ your visible hostname so that the install doesn't
b0rk. But do you really need to set visible_hostname? The implication
of the messages, to me, seems to be that if it can find a proper FQDN
from "hostname -f" (or equivalent) you should be able to get by without
pre-configuring visible_hostname.

Sorry, I don't mean to make it sound like an argument. I was just
telling you what I've run into while configuring it on Linux and FreeBSD
in the past.

No, I didn't think you were arguing, I just wondered if the visible_hostname
absolutely has to be set, or if it's only needed if squid can't find the
FQDN otherwise. So there was only one thing to be done - install it and
find out...

Personally I'm not sure hostname -f would always work on every platform
(or guarantee it would always work), so maybe that's why it's avoided.

gethostname always has to work on a 'nix system, and "hostname" just uses
that.

Also the proxy could be set up to work as a virtual host or a forwarder
chained to other systems, so it may not be good to "autoconfigure" it
out of fear that it'll bork up what you're trying to do.

Except that the message suggested to me that it _does_ try to
autoconfigure - and only uses visible_hostname if it can't find an FQDN.
Having now installed squid, and not having had any kind of error, I can see
that in fact if you have a valid FQDN set, it doesn't
need "visible_hostname" (in fact, /etc/squid/squid.conf says so).

Squid is
really really flexible in deployment, so the maintainer may have opted
to support the lowest common denominator.

Still, if all you need is one variable to be set (visible_hostname) that's
exactly what debconf is for.
