The cryptroot script always uses plymouth if present (plymouth is installed by default on Ubuntu).
Unfortunately this prevents to unlock an encrypted root from console (e.g. via SSH).

Changes in /usr/share/initramfs-tools/scripts/local-top/cryptroot
- new parameter "noplymouth": possible to use during boot time to avoid usage of plymouth even if present
- kill all plymouth processes with "ask-for-password" after encrypted root is available

New file /usr/share/initramfs-tools/hooks/cryptroot_unlock.sh
- creates /bin/unlock script in initramfs to define correct PATH and call cryptroot script with correct parameter
- creates /etc/motd file in initramfs to inform user about unlock script

Kind regards
