I have in a new machine (as on all other boxes) in make.conf
PORTAGE_ELOG_MAILSUBJECT="package \${PACKAGE} merged on \${HOST} with notice"
In /etc/conf.d/hostname
hostname="syscon3"
But when a package is emerge I receive via email notice as in subject line:
"...merged on localhost.localdomain"
eg: package dev-vcs/git-2.26.2 merged on localhost.localdomain with notice
Which file define "${HOST}"
