>Description:
Starting an rc.d script without the corresponding rcvar variable set in rc.conf will silently fail. Printing a notice would be more helpful.
>How-To-Repeat:
# /etc/rc.d/ftpd start
#

.. but ftpd is not started
>Fix:
This patch to /etc/rc.subr notifies the user if the rc.d script is called without the rcvar set.

# diff rc.subr.orig rc.subr
608a609
 >                       echo "$name not started. Set ${rcvar} to YES in 
/etc./rc.conf or use '$name onestart'."


which gives the output:

# /etc/rc.d/ftpd start
ftpd not started. Set ftpd_enable to YES in /etc./rc.conf or use 'ftpd 
onestart'.
