BUGS
       The locations of	files  are  subject  to	 change	 without  notice;  the
       organization of your file system	may vary.

       This list is incomplete.

       The  Network Information	Service	(NIS) was formerly known as Sun	Yellow
       Pages (YP).  The	functionality of the two remains the  same;  only  the
       name has	changed.
