Overview

A system service that may be used as a mechanism to change the system's hostname. systemd-hostnamed is automatically activated on request and terminates itself when it is unused. It seem to be related to dbus-org.freedesktop.hostname1.service.

/etc/hostname

The daemon writes (overwrites) /etc/hostname via hostnamectl. Also see Linux Hostname /etc/hostname.
