- removed /usr/sbin/daemon's option "-t" (first appeared in FreeBSD 11, leading to an error in previous versions; since the [t]itle defaults to the daemonized invocation anyways, this shouldn't make a difference for FreeBSD 11+)
- removed /usr/sbin/daemon's option "-u" and the respective variable in the script (ympd has to be started as root to be able to bind to port 80)
- allow for additional arguments via ympd_flags="" in rc.conf (which would again allow to drop privileges after binding to the port)
init script: depend on $remote_fs instead of $local_fs. Reason: /usr can
be mounted a remote filesystem. Also depend on mpd (instead of $mpd,
which doesn't seem to exist.. at least on my system)
Also provide a default config (which should be installed as
/etc/default/ympd)
This commit makes the systemd unit file as well as the init script load
values from this configuration file so the user can change ympd settings
easily when running it as a service.
