Oh, I was referring to links like these on Ubuntu 22.04:

$ ls -l /usr/share/zoneinfo/Europe/Belfast

lrwxrwxrwx 1 root root 6 Mar 21 11:29 /usr/share/zoneinfo/Europe/Belfast 
-> London

I was not talking about /etc/localtime, which is a different kettle of fish.

PS. Based on my misreading of a quick Google search I said in that quote 
above that macOS uses hard links for aliases like Europe/Belfast. 
However, Guy just reported[1] that current Ventura beta uses copies, 
just like FreeBSD does. Apologies for the error.
