After having read this thread, here's the conclusion I've come to:

	- I agree that it's a potentially hazardous situation to allow
	  uid 0 (or gid 0) in passwd file YP inclusions.

	- I hesitate to disallow uid 0 (or gid 0) in the C library, since
	  it's conceivable that someone might actually _want_ to do that
	  (certainly, that's the case with gid 0).

So, given that I don't want to do what I consider breaking the C library, I'll
add a warning to pwd_mkdb to emit a warning to stderr if an inclusion with
uid 0 or gid 0 is encountered.

As my vacation message says, I'm in Pittsburgh doing demos with our facility
at Supercomputing '96.  This implies that I'm not going to have time to
work on it until Moday, probably.  If someone wants to implement that change,
and send me a patch, gosh, that'd be really cool :-)
