problems entering geli password during boot

[warudemaru]

Thats why I enabled kern.geom.eli.visible_passphrase="1" to use GELI which prevents me from using my computer in conferences or whenever someone else sits next to me

The solution may be quite simple and I wonder why geli developer didn't include it from the beginning as I suppose that implementations of crypted FS in other systems have always visible but starred password, and that can be achieved easily with just few lines listed below. I use kernel patched that way and it seems nothing else is broken.

Now in /boot/loader.conf

kern.geom.eli.visible_passphrase=2

(or any value greater than 1) to get starred password. Now it's easier to control which letters are really typed and which need to be retyped as no star is printed.
