One Key File for Many Users

[Martin G. McCormick]

	One way to allow account-holders on a system to be able
to do nsupdates is to place the keys in each user's directory but this
makes changing the keys later a laborious task. 
Is there a proper way to create links to one key that will
produce the same effect?
	I seem to recall trying something like that some time
ago and having the updates fail because the key referenced was a
link.

Thank you.
