This hook loads osk-sdl to decrypt the filesystem. Used on touchscreen devices like tablets and phones to provide an on screen keyboard in order to enter in a passphrase for decrypting encrypted systems when an keyboard is not present.

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.
