164
normally written to /etc/mandos for later installation into the
170
initrd image, but this, and most other things, can be changed
171
with command line options.
174
This program can also be used with the
175
<option>--password</option> or <option>--passfile</option>
176
options to generate a ready-made section for
177
<filename>clients.conf</filename> (see

command line options.
