+ 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.
