+         If you say Y here, then the kernel will try to autodetect raid
+         arrays as part of its boot process. 
+
+         If you don't use raid and say Y, this autodetection can cause 
+         a several-second delay in the boot time due to various
+         synchronisation steps that are part of this step.
