[Michael A Peters]

Quick question -

Pam update created a new config file as rpmnew

To my knowledge - I've not fuddled with that file.
Is there any reason anyone can think of not to cat the new file on top
of the old? I'm not a pam guru and I'm not sure I understand the changes
or if they are critical.
