That might behave different than expected when current state of the
daemon and the boot configuration differ: for example the sequence above
will start the daemon if it was not running before but is configured to
start at boot; or it will stop the daemon if it was manually started but
is not configured to start automatically at boot.

systemctl has a `try-restart` option that might be helpful in such
cases, but this is optional for LSB init scripts (yay...).  `reload`
would also work if supported.
