If I'm confused, probably other readers are. Maybe you could expand this article a little bit to explain why accessing the installation files with no user interface is important. I'm not dumping on this ... just can't figure out how this is better (maybe I'm dense!)
Is it merely the ability to access the installation file from a command-line?
