What you're asking for would be incredibly difficult. It could be done, but
not with Plymouth, and not without increasing the size of initramfs by several
10s of not 100s of MB. Right now, Plymouth doesn't handle input. Well, it
does, but not most things. It's actually the underlying vtty that handles
input of the passphrase.
You mean, that when plymouth comes on, there is no real UI system that
could handle mouse events, which are needed
to simulate a osk. But that can't honestly be so much hassle, as we
don't need a full featured mouse handler, a simple one would be enough:
leftclick, mouse move thats it.
A font to render all the possible keyboardlayouts will take much more
space and should be limited to the one the system uses+ a default one
with "most used language" support.
M$ has added a simple OSK on boot in it's bios, so you can select
things in touchmode before the real os is running. Not very shiny, not
perfect, but there if needed. A little bit better should "our" system
be, but i don't expect complains, if it isn't a super smooth running
system with cutting edge graphics ;)
On the other hand, as android is capable of FDE, they must have made
some importanted changes that can be of use here.
