 # easily adapted to read /etc/mtab or similar.

+# ADDENDUM:  The addition of the --filter option (which has support for
+# absolute-anchored excludes) has made this script less useful than it
+# was.  Beginning with 2.6.4, you can achieve the effect of this script
+# through this command:
+#
+# awk '{print $2}' /proc/mounts | rsync -f 'merge,/- -' host:/dir /dest/
