tag 477092 + patch
thanks
Here's now a patch which adds support to set a username and password for
GRUB 2
The debconf templates probable need to be changed. I'm not that perfect
in writing them.
And I wasn't sure what to do if people enter a username but no password.
Now I just don't set anything if no password has been given just like
with grub-legacy.
