- Updated xfs pre script to check for the existance of the old monolithic
        /usr/X11R6/lib/X11/fs/config xfs config file, and set a migration flag
        file.
    - Updated xfs.init to check for the existance of the migration flag file,
        and perform an xfs 'restart' instead of a 'reload' if migrating. Users
        will now have to restart their X server, or reconnect the xfs server to
        the X server after a migration to modular X.
    - Changed upgrade comparison typo from 2 to 1 in xfs post script.
