129
      >mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>

      to get a password.  It uses IPv6 link-local addresses to get
 
131
      network connectivity, Zeroconf to find the server, and TLS with
 
132
      an OpenPGP key to ensure authenticity and confidentiality.  It

169
      impossible to enter the encrypted root disk password at the
 
170
      console, since this program does not read from the console at
