+         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.
