      To use this program for its intended purpose (see <xref
433
      linkend="purpose"/>), the password for the root file system will
434
      have to be given out to be stored in a server computer, after
435
      having been encrypted using an OpenPGP key.  This encrypted data
436
      which will be stored in a server can only be decrypted by the
437
      OpenPGP key, and the data will only be given out to those
438
      clients who can prove they actually have that key.  This key,
439
      however, is stored unencrypted on the client side in its initial
440
      <acronym>RAM</acronym> disk image file system.  This is normally
441
      readable by all, but this is normally fixed during installation
442
      of this program; file permissions are set so that no-one is able
443
      to read that file.

446
      The only remaining weak point is that someone with physical
447
      access to the client hard drive might turn off the client
448
      computer, read the OpenPGP keys directly from the hard drive,
449
      and communicate with the server.  The defense against this is
450
      that the server is supposed to notice the client disappearing
451
      and will stop giving out the encrypted data.  Therefore, it is
452
      important to set the timeout and checker interval values tightly
453
      on the server.  See <citerefentry><refentrytitle
454
      >mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>.

      It will also help if the checker program on the server is
