<title>DESCRIPTION</title>
132
<command>&COMMANDNAME;</command> is a program which is meant to
133
be specified as <quote>keyscript</quote> in <citerefentry>
134
<refentrytitle>crypttab</refentrytitle>
135
<manvolnum>5</manvolnum></citerefentry> for the root disk. The
136
aim of this program is therefore to output a password, which
137
then <citerefentry><refentrytitle>cryptsetup</refentrytitle>
138
<manvolnum>8</manvolnum></citerefentry> will use to try and
139
unlock the root disk.
142
This program is not meant to be invoked directly, but can be in
143
order to test it. Note that any password obtained will simply
144
be output on standard output.

<xi:include href="overview.xml"/>
312
This program will run on the client side in the initial
313
<acronym>RAM</acronym> disk environment, and is responsible for
314
getting a password. It does this by running plugins, one of
315
which will normally be the actual client program communicating
319
<refsect1 id="plugins">
320
<title>PLUGINS</title>
322
This program will get a password by running a number of
323
<firstterm>plugins</firstterm>, which are simply executable
324
programs in a directory in the initial <acronym>RAM</acronym>
325
disk environment. The default directory is
326
<filename>/lib/mandos/plugins.d</filename>, but this can be
327
changed with the <option>--plugin-dir</option> option. The
328
plugins are started in parallel, and the first plugin to output
329
a password and exit with a successful exit code will make this
330
plugin-runner output that password, stop any other plugins, and
