With usplash it is pretty easy to implement. However the problem is that
it will work with usplash and usplash only. If you disable usplash its
behaviour will still be the same. The problem is that without usplash
the cryptsetup binary is fetching the password from console directly -
leaving no chance to buffer it in an environment variable. However since
most people will use usplash, it will at least fix it for them. Another
unsolved issue is that not all entries from /etc/crypttab are handled by
the initramfs but later in the bootprocess by /etc/init.d/cryptdisks-
early & co. So one would probably need to move all entries from crypttab
to initramfs.
The small fix described above: you have to modify
/usr/share/initramfs-tools/scripts/local-top/cryptroot.
