-- help
-- 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.
