Implementing roaming user profile on Linux.

• There is a local copy of the user profile, say at /usr/local/DOMAIN/user, and
• There is a remote copy of the user profile, stored on a central server and mounted on the local system, say at /usr/roaming/DOMAIN/user.

The task is to keep these profiles in sync.
