Nor am I, especially after this. According to apt-file, it is in the
package systemd.

I confirm this. I guess I missed it due to rarely referring to a
computer by its hostname, but instead by localhost. Sigh. Thanks for
the catch. It looks like I shall have to adjust my installation scripts.

Odd. On the two boxes I used hostnamectl on, mailname is set correctly.
However, I ran it on installation, and may have fixed that manually
(but there's no backup file), or by installing postfix subsequently.

I run it in a script that I run manually immediately after installation.

Yup. However I make sure they agree by assigning most hosts a "host"
statement in dhcpd.conf, and assigning a fixed IP address to a given MAC
address, and then having dhcpd feed that to bind9.
