Thanks for doing this, Ben.

I'll eagerly wait feedback from the Plymouth maintainers on how to help
them debug this further :)

No, that's not it. I've had Plymouth installed since ever. FWIW, here
are the plymouth packages I've installed on my machine:

  dpkg -l '*plymouth*'

No idea why old kernel versions weren't calling plymouth to ask for the
luks password.

Just in case: is "dpkg --purge plymouth" supposed to be a safe way out
of this bug these days? Or do we now require plymouth in order to be
able to ask for luks password during boot?

Cheers.
