+          Give the number of Blocks to reserve for checkpointing.
+	  Checkpointing saves the state at unmount so that mounting is
+	  much faster as a scan of all the flash to regenerate this state
+	  is not needed.  These Blocks are reserved per partition, so if
+	  you have very small partitions the default (10) may be a mess
+	  for you.  You can set this value to 0, but that does not mean
+	  checkpointing is disabled at all. There only won't be any
+	  specially reserved blocks for checkpointing, so if there is
+	  enough free space on the filesystem, it will be used for
+	  checkpointing.
+
+	  If unsure, leave at default (10), but don't wonder if there are
+	  always 2MB used on your large page device partition (10 x 2k
+	  pagesize). When using small partitions or when being very small
+	  on space, you probably want to set this to zero.
