+//config:	  fdflush is only needed when changing media on slightly-broken
+//config:	  removable media drives. It is used to make Linux believe that a
+//config:	  hardware disk-change switch has been actuated, which causes Linux to
+//config:	  forget anything it has cached from the previous media. If you have
+//config:	  such a slightly-broken drive, you will need to run fdflush every time
+//config:	  you change a disk. Most people have working hardware and can safely
+//config:	  leave this disabled.

+//config:	  Linux allows you to create ramdisks. This utility allows you to
+//config:	  delete them and completely free all memory that was used for the
+//config:	  ramdisk. For example, if you boot Linux into a ramdisk and later
+//config:	  pivot_root, you may want to free the memory that is allocated to the
+//config:	  ramdisk. If you have no use for freeing memory from a ramdisk, leave
+//config:	  this disabled.
