I believe that you are asking to make a shortcut as in Windows?
I would advise against it because the / directory is usually very small and you would fill it up quickly if you get alot of mail.
However, if you still want to do this, you can use the ln command.
ln -s /var/spoo/mail/root /mail.root
My suggestion is to install elm or use the builtin mail command to check your mail. Just type "mail" at the prompt.
I would even suggest using .forward to send your emails that go to root over to Outlook or Outlook Express on your PC or laptop. This is the way that I monitor all myemail for 14 boxes.
