I think it reasonable to limit the adjustments made to /var/yp/Makefile
within system-config-nis to those things which are normal user
configurable options.
If you take a look at your own Makefile, I want to limit GUI
configuration controls to those things above the warning:
DON'T EDIT ANYTHING BELOW IF YOU DON'T KNOW WHAT YOU ARE DOING !!!
It's probably safe to assume that anyone who would be editing beyond
that point would be doing things by hand.
