# FreeBSD rc.d service for RSPlayer.
#
# Add the following to /etc/rc.conf to enable the service:
#
#   rsplayer_enable="YES"
#   rsplayer_user="salmon"     # user to run the daemon as (NOT root)
#   rsplayer_group="wheel"     # group of that user
#
# rsplayer_user must be a regular user: the daemon socket and PID file live
# in rsplayer_runtime_dir (default /tmp/rsplayer, matching the daemon's
# fallback when XDG_RUNTIME_DIR is unset) and the `rsp` CLI connects to that
# socket, so the daemon and the CLI must run as the same user.
#
# Optional: rsplayer_runtime_dir="/tmp/rsplayer"

# PROVIDE: rsplayer
# REQUIRE: LOGIN dbus
# KEYWORD: shutdown
