I've commited this patch with updates, but there is one problematic
part of the code left.  This code in
debian-edu-config/share/debian-edu-config/d-i/pre-pkgsel:

        cat > $file <<EOF
debian-edu-config debian-edu-config/kdc-password password $ROOTPWD
debian-edu-config debian-edu-config/kdc-password-again password $ROOTPWD
debian-edu-config debian-edu-config/ldap-password password $ROOTPWD
debian-edu-config debian-edu-config/ldap-password-again password $ROOTPWD
debian-edu-config debian-edu-config/first-user-name string $FIRSTUSERNAME
debian-edu-config debian-edu-config/first-user-fullname string $FIRSTUSERGECOS
debian-edu-config debian-edu-config/first-user-password password $FIRSTUSERPWD
EOF
        # Pass user and password information into the target
        cat $file | LANG=C chroot /target debconf-set-selections || \
            error "Failed to load preseed values from $file."
        rm $file

The problem is with '#' in the password and debconf-set-selections.
debconf-set-selections will stop processing when it find a #, causing

  debian-edu-config debian-edu-config/first-user-password password #secret

to be read like

  debian-edu-config debian-edu-config/first-user-password password 

This in turn make the code setting up the first user pick the root
passoword as the first users password because no password were
provided.  If the root password contain #, the resulting password
might be empty (I am not sure, have not tested).  Neither is good. :)

But I am unable to find a way to quote # in passwords that
debconf-set-selections. will accept.  Anyone got any ideas?
