FreeBSD offers yet another obstacle to Andrew's proposal:
$ uname -a
FreeBSD rpi3.sss.pgh.pa.us 12.0-RELEASE FreeBSD 12.0-RELEASE r341666 GENERIC arm64
$ ls /usr/share/zoneinfo/
Africa/ Australia/ Etc/ MST WET
America/ CET Europe/ MST7MDT posixrules
Antarctica/ CST6CDT Factory PST8PDT zone.tab
Arctic/ EET HST Pacific/
Asia/ EST Indian/ SystemV/
Atlantic/ EST5EDT MET UTC
No zone1970.tab. I do not think we can rely on that file being there,
since zic itself doesn't install it; it's up to packagers whether or
where to install the "*.tab" files.
In general, the point I'm trying to make is that our policy should be
"Ties are broken arbitrarily, and if you don't like the choice that initdb
makes, here's how to fix it". As soon as we try to break some ties in
favor of somebody's idea of what is "right", we are in for neverending
problems with different people disagreeing about what is "right", and
insisting that their preference should be the one the code enforces.
Let's *please* not go there, or even within hailing distance of it.
(By this light, even preferring UTC over UCT is a dangerous precedent.
I won't argue for reverting that, but I don't want to go further.)
