+  This hook loads the necessary modules for any raid root device,
+  and assembles the raid device when run.
+
+  If arrays are defined in /etc/mdadm.conf, the file will be used instead
+  of command line assembling.
+  
+  Command Line Setup:
+  - for raid arrays with persistent superblocks:
+    md=<md device no.>,dev0,dev1,...,devn
+    md=<md device no.>,uuid
+  - for partitionable raid arrays with persistent superblocks:
+    md=d<md device no.>,dev0,dev1,...,devn
+    md=d<md device no.>,uuid
+
+  Parameters:
+  - <md device no.> = the number of the md device: 
+    0 means md0, 1 means md1, ...
+  - <dev0-devn>: e.g. /dev/hda1,/dev/hdc1,/dev/sda1,/dev/sdb1
+                   or 0900878d:f95f6057:c39a36e9:55efa60a
+  Examples:
+  - md=d0,/dev/sda3,/dev/sda4 md=d1,/dev/hda1,/dev/hdb1
+    This will setup 2 md partitionable arrays.
+  - md=0,/dev/sda3,/dev/sda4 md=1,/dev/hda1,/dev/hdb1
+    This will setup 2 md arrays with persistent superblocks.
