# For people who run dmcrypt on top of some other layer (like raid),

# 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.
|
||||
# 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'

# way into unencrypted swap.

# If no makefs is given then mkswap will be assumed

## Loopback file example

#source='/dev/loop0'

#loop_file='/mnt/crypt/home'
