No. This actually depends very much on the distribution. In any case,
during the startup the machine will at some point call the programs
"hostname" - which sets the hostname (in your case, "localhost") -
and a program called either "domainname" or "dnsdomainname" - which
sets the domain name (in your case, "localdomain").
AFAIK, "localhost" is a reserved word. This is not true for "localdomain".

That might work.

The files /etc/hosts.allow and /etc/hosts.deny are queried in the order
hosts.allow --> hosts.deny. That means, if a host is found in hosts.allow,
access is allowed. Else, if the host is found in hosts.deny, access is
denied. If a host is not found in either file, access is allowed.
This means that, if you put
into /etc/hosts.allow, the behaviour of /etc/hosts.deny will not be
affected. However, you can write
into /etc/hosts.deny - just to make sure that nobody is able to somehow
spoof "LOCAL" (although I have no idea how one would try to do that).

No. As explained above, "localhost" points always (?) to 127.0.0.1 which
incidentally is a reserved IP number of your machine.

Leafnode does not use this file; however, a number of news clients (e.g.
tin) do. Some startup scripts also obtain the value of $NNTPSERVER
(which is a shell variable, not a link) from this file. Again, this
depends on your distribution. You can see the current value of
$NNPTSERVER by typing at the shell prompt
Hope that helps,
