>Environment:

	2.0.5 Release kernel.

>Description:

	It seems to me that the CHILD_MAX in the default configurations is
	a bit small, even for a single user machine: someone running X 
	can easily wander over 40 processes.

>How-To-Repeat:

	Compile from a GENERIC kernel.

>Fix:
	
	I'd suggest putting

# Under some circumstances it is necessary to make the default max
# number of processes per user and open files per user more than the
# defaults on bootup.  (an example is a large news server in which
# the uid, news, can sometimes need > 100 simultaneous processes running,
# or perhaps a user using lot's of windows under X).
options  "CHILD_MAX=64"  
options  "OPEN_MAX=128"

	into the GENERIC configuration, so that new users working from that
	as a reference will find it when they're rebuilding their kernel,
	rather than actually having to think about it. :-)
