Massive everywhere: what are your favorite conventions for computers and devices around the home and office?

Of late I've been going with Hebridean islands for system names, Star Wars critters for IP cameras (because one of the first ones I installed reminded me vaguely of a Jawa), and characters from and the Holy Grail for other minor network-enabled microcontroller-based gizmos.

I definitely need to start a process of not committing to a until I've typed it a dozen times at different levels of tiredness, etc. Named a system 'igneous' and by damn it's a PITA to type more than 50% of the time for me. Stupid Rocky Linux.

Try this on for size. It's what the command actually does, what's actually common with all other operating systems (even HP-UX), and what it deprecates is what the Tobias hostname(1) manual has been deprecating since around the turn of the century.

Many guides even for Debian actually stick to the conventional use. This one has "linux.example.com" as the hostname from "hostname" and "hostname -s" shortening it.

This is, ironically, why the old confusing hostname(1) manual has all of these backpedallings about not using "hostname -fqdn". It's a misfeature that no other implementation has, invented peculiarly for Debian and the peculiar Debian notion that we still live in 1981.

The Debian command was done badly in the middle-1990s, and the hostname(1) manual has been trying to un-dig the hole ever since, the hostname(7) manual having the real 40-year convention.

Since the 1980s, everyone else has been happy to have and document multi-label names as the norm.

RedHat's doco, for example, has almost equally long said to use a multiple-label name as the hostname. Just like the actual Unix operating systems all did before it.

RHEL 9 says "new-hostname.example.com" for example.

On the contrary, multiple-label hostnames work with most softwares, even UUCP being able to have multiple-label names in bang paths, because it's been the convention since at least 1983.

Debian has had this wrong for a long time.

Debian's focus on putting a short hostname in and letting the HOSTS file expand it using name qualification and canonicalization mechanisms is straight out of the pre-DNS times.

Interesting factoid:

The HP-UX manual is about the only one to describe a convention of the UUCP node name (available via uname(1) and uname(2)) as a distinctly configurable thing separate from the Unix hostname. (It's almost universally the same thing under the covers in modern Unices and Linux distributions nowadays.)

The HP-UX hostname(1) has a table with the UUCP nodename as "sys" and the Unix hostname as "sys.x.y.z...".

On the subject of UUCP and nostalgia:

I actually glanced at the rmail(1) manual page this month. Not because I was going to use it, mind.

I was trying to find the earliest that it became the norm to use a multiple-label name as a Unix hostname, something that happened pretty soon after the advent of the DNS.

The 4.2BSD manual has that convention described, with the infamous "monet.Berkeley.EDU". So too does the SCO Unix System 5 Release 3 manual.
