Previously we just wrote /etc/hostname and returned. The kernel hostname was left at whatever PID 1 sethostname()'d very early in boot (before /etc/hostname existed), which meant hostnamectl reported the transient hostname instead of the static one until the next reboot. Call io.systemd.Hostname.SetStaticHostname on the running system so hostnamed writes /etc/hostname and updates the kernel hostname in one step. If hostnamed is unreachable (masked or absent on minimal images) fall back to writing /etc/hostname directly. --root=/--image= also keeps writing the file directly, since hostnamed only manages the running system.
