That would mean that I could see a bunch of certificates from all the 
servers in the autokey hierarchy. Is there a chance or a collection of 
data that shows me how exactly the hierarchy looks like (i.e. which

Log files are great for finding out what has happened when but I do 
think they are useful for determining the current status of something.
