To my mind, the proper solution is to move the /etc/rc.d/ypset  
functionality into /etc/rc.d/ypbind, and eliminate /etc/rc.d/ypset  
altogether.  ypset(8) is only ever consumed by ypbind(8), so  
splitting them apart like this just adds needless complexity.

I would eliminate the nis_ypset_enable rc.conf variable, and have / 
etc/rc.d/ypbind invoke ypset(8) directly if nis_ypset_flags is not  
empty.
