This hook allows for startup decryption of multiple dm-crypt luks encrypted |
|
devices. Users should specify the devices to be unlocked using: |
|
|
|
'multidecrypt=device[[:device]...]' |
|
|
|
on the kernel command line, where 'device' is the path to the raw device, |
|
specified using PARTUUID or some other means. Devices will be available as |
|
/dev/mapper/container[1,2,3...] etc. |
|
|
|
The hook expects a dm-crypt luks encrypted file called /boot/${KEYFILE_NAME} to |
|
exist. This keyfile contains a concatenation of 4096 bit keys for each |
|
encrypted device in the same order as specified in the multidecrypt kernel |
|
command line argument. |
|
|
|
If decryption of one of the devices fails, the hook will attempt to continue |
|
to decrypt any other specified devices. This is useful for btrfs software |
|
raid if a device has failed as an example. |
|
|
|
You will be prompted for the password to the ${KEYFILE_NAME} container 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. |
