	Gnodes are our version of Sun's vnodes.  It's a handy
	mechanism for supporting mutiple file systems.  The
	gnode table is sized based on the values of "maxusers"
	and the size of the proc table and text table.  If you
	increase maxusers in the configuration file and rebuild
	you'll get a large gnode table (and proc table and text
	table and...).

    The obligitory maxusers comment.

	The configuration file parameter maxusers isn't connected
	with the number of users licensed to login.  Maxusers is
	used to determine the size of various system tables.  If
	you want bigger tables, raise maxusers.  It won't change
	the number of people allowed to login.

	In the Summer 1986 USENIX Conference Proceedings there is
	a paper, "The Generic File System", by Robert Rodriguez,
	Matt Koehler and Richard Hyde.  There is also another
	paper in the Summer 1987 USENIX Conference Proceedings,
	"GFS Revisited -or- How I Lived with Four Different Local
	File Systems".  You should find these interesting reading.
