This hook allows for an encrypted root device. 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.
|
||
|
|
|
||
|
|
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.
