165
normally written to /etc/mandos for later installation into the
172
initrd image, but this, and most other things, can be changed
173
with command line options.
176
This program can also be used with the
177
<option>--password</option> or <option>--passfile</option>
178
options to generate a ready-made section for
179
<filename>clients.conf</filename> (see

command line options.
