Thanks for that.  I only picked up on rear this morning, I suppose if 
you don't go looking for it you'll never find it.  A combination of the 
paper Site Management Guide and the nightly disk summary have worked for 
over 20 years on *NIX!  VMS before that was totally different, but we 
still kept paper copies of configuration.
