+This hook allows for an encrypted root device. Users should specify the device
+to be unlocked using 'cryptdevice=device:dmname' on the kernel command line,
+where 'device' is the path to the raw device, and 'dmname' is the name given to
+the device after unlocking, and will be available as /dev/mapper/dmname.
+
+For unlocking via keyfile, 'cryptkey=device:fstype:path' should be specified on
+the kernel cmdline, where 'device' represents the raw block device where the key
+exists, 'fstype' is the filesystem type of 'device' (or auto), and 'path' is
+the absolute path of the keyfile within the device.
+
+Without specifying a keyfile, you will be prompted for the password at runtime.
+This means you must have a keyboard available to input it, and you may need
+the keymap hook as well to ensure that the keyboard is using the layout you
+expect.

+	# A disk log ensures that a mirror LV does not need to be
+	# re-synced (all copies made the same) every time a machine
+	# reboots or crashes.
+	# If a device in the LV fails, this policy determines the
+	# steps perfomed by dmeventd automatically, and the steps
+	# performed by 'lvconvert --repair --use-policies' run manually.
+	# Automatic handling requires dmeventd to be monitoring the LV.
+	# Possible options are: remove, allocate, allocate_anywhere.
+	# remove - Simply remove the faulty device and run without it.
+	# If the log device fails, the mirror would convert to using
+	# an in-memory log.  This means the mirror will not
+	# remember its sync status across crashes/reboots and
+	# the entire mirror will be re-synced.
+	# If a mirror image fails, the mirror will convert to a
+	# non-mirrored device if there is only one remaining good copy.
+	# allocate - Remove the faulty device and try to allocate space
+	# on a new device to be a replacement for the failed device.
+	# Using this policy for the log is fast and maintains the
+	# ability to remember sync state through crashes/reboots.
+	# Using this policy for a mirror device is slow, as it
+	# requires the mirror to resynchronize the devices, but it
+	# will preserve the mirror characteristic of the device.
+	# This policy acts like 'remove' if no suitable device and
+	# space can be allocated for the replacement.
+	# allocate_anywhere - Not yet implemented. Useful to place
+	# the log device temporarily on the same physical volume as

+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.
