+ 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.
