This hook allows for multiple encrypted root devices. Users should specify the
|
||
|
|
device to be unlocked using 'cryptdevice=device:dmname' on the kernel command
|
||
|
|
line, where 'device' is the path to the raw device, and 'dmname' is the name
|
||
|
|
given to the device after unlocking, and will be available as /dev/mapper/dmname.
|
||
|
|
|
||
|
|
Subsequent devices must be specified the same way, but with cryptdevice1=,
|
||
|
|
cryptdevice2= and so on, in order. Passwords will be cached and attempted to
|
||
|
|
re-use them on the next device, and if that fails, a new password will be asked
|
||
|
|
for.
|
||
|
|
|
||
|
|
For unlocking via keyfile, 'cryptkey=device:fstype:path' should be specified on
|
||
|
|
the kernel cmdline, where 'device' represents the raw block device where the key
|
||
|
|
exists, 'fstype' is the filesystem type of 'device' (or auto), and 'path' is
|
||
|
|
the absolute path of the keyfile within the device.
|
||
|
|
|
||
|
|
Without specifying a keyfile, you will be prompted for the password 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.
