The argument passed from "splash" to "nosplash" in debian by default. I
did try to reintroduce backward compatibility and this case handling. I
may have missed some parts (reminder: 150+ files difference), and that
was not the intend.
Remember as well that the description is made from most of the diff I
could understand. Indeed, even recent patches from people uploading
plymouth in ubuntu included new patches without any description (and not
following DEP3), which was making this merge even harder…

We did try with Martin on a vm when a passphrase was asked from the
start, and didn't see any issue, but that was maybe another case and we
didn't get into that one.

Feel free to amend and change for the expected user experience where the
fundation team feel the needs.

Cheers,
Didier
