+	  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.
