+# For people who run dmcrypt on top of some other layer (like raid),
+# use rc_need to specify that requirement.  See the runscript(8) man
+# page for more information.
+
+#--------------------
+# Instructions
+#--------------------
+
+# Note regarding the syntax of this file.  This file is *almost* bash,
+# but each line is evaluated separately.  Separate swaps/targets can be
+# specified.  The init-script which reads this file assumes that a
+# swap= or target= line starts a new section, similar to lilo or grub
+# configuration.
+
+# Note when using gpg keys and /usr on a separate partition, you will
+# have to copy /usr/bin/gpg to /bin/gpg so that it will work properly
+# and ensure that gpg has been compiled statically.
+# See http://bugs.gentoo.org/90482 for more information.
+
+# Note that the init-script which reads this file detects whether your
+# partition is LUKS or not. No mkfs is run unless you specify a makefs
+# option.
+
+# Global options:
+#----------------
+
+# How long to wait for each timeout (in seconds).
+dmcrypt_key_timeout=1
+
+# Max number of checks to perform (see dmcrypt_key_timeout).
+#dmcrypt_max_timeout=300
+
+# Number of password retries.
+dmcrypt_retries=5
+
+# Arguments:
+#-----------
+# target=<name>                      == Mapping name for partition.
+# swap=<name>                        == Mapping name for swap partition.
+# source='<dev>'                     == Real device for partition.
+#                                    Note: You can (and should) specify a tag like UUID
+#                                    for blkid (see -t option).  This is safer than using
+#                                    the full path to the device.
+# key='</path/to/keyfile>[:<mode>]'  == Fullpath from / or from inside removable media.
+# header='</path/to/header>'         == Full path to detached LUKS header file.
+# remdev='<dev>'                     == Device that will be assigned to removable media.
+# gpg_options='<opts>'               == Default are --quiet --decrypt
+# options='<opts>'                   == cryptsetup, for LUKS you can only use --readonly
+# loop_file='<file>'                 == Loopback file.
+#                                    Note: If you omit $source, then a free loopback will
+#                                    be looked up automatically.
+# pre_mount='cmds'                   == commands to execute before mounting partition.
+# post_mount='cmds'                  == commands to execute after mounting partition.
+# wait=5                             == wait given amount of seconds for source or
+#                                       detached header file appear.
