-dit(bf(-x, --one-file-system)) This tells rsync to avoid recursing into a
-directory that is the mount-point for another filesystem, including (as of
-2.6.7), "bind" mount-points. You can still copy the contents of multiple
-file systems if you include a source dir from each file system -- this just
-limits rsync's directory-recursion algorithm.
+dit(bf(-x, --one-file-system)) This tells rsync to avoid crossing a
+filesystem boundary when recursing. This does not limit the user's ability
+to specify items to copy from multiple filesystems, just rsync's recursion
+through the hierarchy of each directory that the user specified, and also
+the analogous recursion on the receiving side during deletion. Also keep
+in mind that rsync treats a "bind" mount to the same device as being on the
+same filesystem.
