+# - sparse create and use sparse file (the fastest)
+# - dedupplugin use the plugin of the same name to generate a stream of random
+#   chunk $CHUNKSIZE long. More useful when used with dedup because each chunk
+#   is handled individually and create a hash in the index.
+#   The data are random and it is faster than urandom
