[Bug 55159] Re: usplash prevents passwords from being not echoed on the console

POSSIBLE EXPLANATION OF initramfs VS init.d BEHAVIOR:

initramfs=no console under usplash
init.d=active console under usplash

The right fix is to fix askpass.c so that no matter how you use
cryptsetup the passphrase is secure. The bug doesn't exist with a start-
of-boot passphrase call now, but what if the boot sequence changes in
the future to put an active console under usplash in the initramfs?

I experimented with a simple, hardcoded script using usplash_write
INPUTENTER that worked for initramfs passphrase entry, to allow a swap
partition on an LVM volume to give encrypted hibernation. Then, of
course, I found  cryptsetup already handles this fine as released-but
what about possible future boot sequences?

What source package contains the source code for the askpass.c binary? I
wanted to give this a try but never found the source of askpass.c
