It only needs to be started during boot. Starting it at other times shouldn't hurt, except that if systemd-journald is restarting at the same time, the latter might not have a SIGUSR1 signal handler installed yet, so it might be killed by systemd-journal-flush. (At least that's my theory about the dead systemd-journald instances in the build farm...)
