-  This hook loads the necessary modules for any raid root device,
+  This hook adds mdadm to arch boot image.
-  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.

+# mdadm configuration file
+#
+# mdadm will function properly without the use of a configuration file,
+# but this file is useful for keeping track of arrays and member disks.
+# In general, a mdadm.conf file is created, and updated, after arrays
+# are created. This is the opposite behavior of /etc/raidtab which is
+# created prior to array construction.
+#
+#
+# the config file takes two types of lines:
+#
+#	DEVICE lines specify a list of devices of where to look for
+#	  potential member disks
+#
+#	ARRAY lines specify information about how to identify arrays so
+#	  so that they can be activated
+#
+
+
+# You can have more than one device line and use wild cards. The first 
+# example includes SCSI the first partition of SCSI disks /dev/sdb,
+# /dev/sdc, /dev/sdd, /dev/sdj, /dev/sdk, and /dev/sdl. The second 
+# line looks for array slices on IDE disks.
+#
+#DEVICE /dev/sd[bcdjkl]1
+#DEVICE /dev/hda1 /dev/hdb1
+#
+AUTO -imsm -ddf
+# The designation "partitions" will scan all partitions found in
+# /proc/partitions
+DEVICE partitions
+
+
+# ARRAY lines specify an array to assemble and a method of identification.
+# Arrays can currently be identified by using a UUID, superblock minor number,
+# or a listing of devices.
+#
+#	super-minor is usually the minor number of the metadevice
+#	UUID is the Universally Unique Identifier for the array
+# Each can be obtained using
+#
+# 	mdadm -D <md>
+#
+# To capture the UUIDs for all your RAID arrays to this file, run these:
+#    to get a list of running arrays:
+#    # mdadm -D --scan >>/etc/mdadm.conf
+#    to get a list from superblocks:
+#    # mdadm -E --scan >>/etc/mdadm.conf
+#
+#ARRAY /dev/md0 UUID=3aaa0122:29827cfa:5331ad66:ca767371
+#ARRAY /dev/md1 super-minor=1
+#ARRAY /dev/md2 devices=/dev/hda1,/dev/hdb1
+#
+# ARRAY lines can also specify a "spare-group" for each array.  mdadm --monitor
+# will then move a spare between arrays in a spare-group if one array has a
+# failed drive but no spare
+#ARRAY /dev/md4 uuid=b23f3c6d:aec43a9f:fd65db85:369432df spare-group=group1
+#ARRAY /dev/md5 uuid=19464854:03f71b1b:e0df2edd:246cc977 spare-group=group1
+#
+
+
+# When used in --follow (aka --monitor) mode, mdadm needs a
+# mail address and/or a program.  To start mdadm's monitor mode, enable
+# mdadm.service in systemd.
+#
+# If the lines are not found, mdadm will exit quietly
+#MAILADDR root@mydomain.tld
