Fundamentals
============
The fundamental concept behind Amd is the ability to separate the
name used to refer to a file from the name used to refer to its physical
storage location. This allows the same files to be accessed with the
same name regardless of where in the network the name is used. This is
very different from placing `/n/hostname' in front of the pathname
since that includes location dependent information which may change if
files are moved to another machine.
By placing the required mappings in a centrally administered
database, filesystems can be re-organised without requiring changes to
configuration files, shell scripts and so on.
