Not only that, but the server wouldn't necessarily notice when a user
modifies a file on the 'exported' filesystem. As a result it would not
break callbacks to inform client that a file was updated. And because
the file isn't marked as a newer version, it could be overwritten by a
client that can't tell there is a conflict, server-server resolution
would not propagate this new version to other servers, and depending on
which server a client pulls the file from he would get either the old or
the 'new' version.

The Coda fileserver simply needs to manage addition, deletion, and
modification of all files in Coda's namespace to be able to guarantee
the proper callback semantics and track consistent version information.
