-         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.
