+ help
+ Give the number of Blocks to reserve for checkpointing. 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.
