Comment 7 for bug 296841

This fix breaks logging into our OpenVZ and Linux-VServer virtual machines created from debootstrapped templates. The routine by which you check whether the root login should be disabled is wrong:

if printf '!\0' | unix_chkpwd root nullok ; then
  echo 'root:!' | chpasswd -e
fi

This should become:

if printf '!\0' | unix_chkpwd root nonull ; then
  echo 'root:!' | chpasswd -e
fi

This bug will affect everybody who has "*" as their root password, hence not using password, hence probably exclusively using SSH keys or something such. This should have been tested better before releasing a package that will lock many people out of their template-created machines (virtual or not).
