[Bug 876626] Re: Unlocking the second crypto disk (/home) echos password on console

[bwalex]

This also affects the first prompt, and there are further issues - the
"press s to skip mounting or m for manual recovery" message appears on
top of the password prompt. You can get around it with pressing esc
several times, but you end up with the same issue of it echoing the
passphrase.

See http://leaf.dragonflybsd.org/~alexh/ubuntu_crypttab.jpg for the
echoing problem.

See http://leaf.dragonflybsd.org/~alexh/ubuntu_plymouth.jpg for the
second issue with the "s or m" message.

The priority of this should be the highest available, as it is a major
security flaw. A fix to this will stop all echoing, not just echo stars.

Cheers,
Alex
