Menu locks / password authentication

[Robert Millan]

It's funny, we're all discussing about performing security measurements in
GRUB and nobody mentioned that our user interface lacks even the most basic
lock mechanism :-)

Perhaps this would be a good time to retake the discussion on implementing
an equivalent to "lock" and "password" commands.  I think I even sent a patch
a while ago!

Vesa, do you still think we should design an extensible framework for
authentication before we do anything else?  I think it'd be interesting if
we could implement the lock/password paradigm, even if later it would be
replaced, since our users commonly need this, and it's blocking the
transition from GRUB Legacy.
