# 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:
+# absolute-anchored excludes) can make this screen unneeded in some
+# scenarios. If you don't need delete protection on the receiving side
+# (or if the destination path is identical to the source path), then you
+# can exclude some absolute paths from the transfer based on the mount
+# dirs. For instance:
#
-# awk '{print $2}' /proc/mounts | rsync -f 'merge,/- -' host:/dir /dest/
+# awk '{print $2}' /proc/mounts | grep -v '^/$' | \
+# rsync -avf 'merge,/- -' /dir host:/dest/
