Sorry, I am not interested in this. We want the hostname initialized to some value very early at boot, so that userspace can rely that the hostname is set at all times, even if that is not the final host name. In most cases it will be the final name, but if in many cases (like the hostname from DHCP usecase) it isn't then this is fine. In your case I'd just recommend removing any configuration of the static hostname entirely. (i.e. remove /etc/hostname and friends). systemd will then just initialize the hostname to "localhost". Then, when you know your "final" hostname, just set it with dbus-send for example. > Make a hostnamed --setfromfile option and use in in a > set-hostname.service file.

In this unit I > can change the /etc/hostname file before the hostname is set. This is all designed so that writes to /etc are never necessary, (i.e. that dir can be mounted read-only). So, when you figure out your network-based hostname, then set the transient hostname to it, not the static one.
