+# /etc/conf.d/dmcrypt
+
+# 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.
+
+# Along the same lines, if dmcrypt needs to be running before
+# localmount or netmount, please use rc_before to specify this
+# requirement.
+
+#--------------------
+# 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.
+# 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.
+#-----------
+# Supported Modes
+# gpg == decrypt and pipe key into cryptsetup.
+# Note: new-line character must not be part of key.
+# Command to erase \n char: 'cat key | tr -d '\n' > cleanKey'
+
+#--------------------
+# dm-crypt examples

+## swap
+# Swap partitions. These should come first so that no keys make their

+# If no makefs is given then mkswap will be assumed
+#swap=crypt-swap
+#source='/dev/hda2'

+#key='/full/path/to/tmpkey'
+#pre_mount='/sbin/mkreiserfs -f -f ${dev}'
+#post_mount='chown root:root ${mount_point}; chmod 1777 ${mount_point}'
+
+## Loopback file example
+#target='crypt-loop-home'
+#source='/dev/loop0'
+#loop_file='/mnt/crypt/home'
+
+# The file must be terminated by a newline. Or leave this comment last.
