Hey Guix

I've asked on IRC if those bugs were known but apparently no, so here
they are:

- during guided installation with LUKS encryption one is not able to
enter password longer then length of field;
- in the same field password is shown during typing (lets one see bug
above, characters typed after reaching length of field are simply
not recorded);

Field with conformation hides typed letters. Due to bug #1 I wasn't
able to check if it works properly.

Good catch!

Commit ef250707d3303d58ae00fe8f461701e7fa788d8a fixes it for the
passphrase, the root password, and user passwords.
