cryptgnupg-sc initramfs script with plymouth locks up pinentry

[Keeley Hoek]

It's great that the `cryptgnupg-sc` keyscript exists and runs out-of-the-box, and it (and its brethren) should be more widely known!

However, `cryptgnupg-sc` prompts using `pinentry-ncurses` which 1. hides behind plymouth so it looks like everything has hung, and 2. actually locks up when you try to enter a password (try it) because (I believe) plymouth captures [ENTER] so you can't actually select OK on the pinentry dialog.

To fix this, I think all that needs to happen is the copy of `pinentry` copied into the initramfs by the `cryptgnupg-sc` hook needs to be replaced. Are the maintainers aware of this project: https://github.com/werwurm/plymentry which essentially does this? (That repository also houses some scripts which are irrelevant for our purposes here.)

Is there scope to ship a tiny binary which replaces pinentry along with `cryptsetup-initramfs`? (GNUPG would be none-the-wiser.) This would make the family of shipped keyscripts work really well just by setting up `/etc/crypttab`, without any initramfs script hacking at all. At the moment it's tantalizingly close!

Kind regards,
Keeley
