<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.
148
<refsect1 id="purpose">
149
<title>PURPOSE</title>
151
The purpose of this is to enable <emphasis>remote and unattended
152
rebooting</emphasis> of client host computer with an
153
<emphasis>encrypted root file system</emphasis>. See <xref
154
linkend="overview"/> for details.
101
<command>&COMMANDNAME;</command> is a plugin runner that waits
102
for any of its plugins to return sucessfull with a password, and
103
passes it to cryptsetup as stdout message. This command is not
104
meant to be invoked directly, but is instead meant to be run by
105
cryptsetup by being specified in /etc/crypttab as a keyscript
106
and subsequlently started in the initrd environment. See
107
<citerefentry><refentrytitle>crypttab</refentrytitle>

Note that since options are not split on whitespace, the

way to pass, to the plugin
223
<quote><filename>foo</filename></quote>, the option

<xi:include href="overview.xml"/>
341
This program will run on the client side in the initial
342
<acronym>RAM</acronym> disk environment, and is responsible for
343
getting a password. It does this by running plugins, one of
344
which will normally be the actual client program communicating
348
<refsect1 id="plugins">
349
<title>PLUGINS</title>
351
This program will get a password by running a number of
352
<firstterm>plugins</firstterm>, which are simply executable
353
programs in a directory in the initial <acronym>RAM</acronym>
354
disk environment. The default directory is
355
<filename>/lib/mandos/plugins.d</filename>, but this can be
356
changed with the <option>--plugin-dir</option> option. The
357
plugins are started in parallel, and the first plugin to output
358
a password <emphasis>and</emphasis> exit with a successful exit
359
code will make this plugin-runner output the password from that
360
plugin, stop any other plugins, and exit.
364
<refsect1 id="fallback">
365
<title>FALLBACK</title>
367
If no plugins succeed, this program will, as a fallback, ask for
368
a password on the console using <citerefentry><refentrytitle
369
>getpass</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
370
and output it. This is not meant to be the normal mode of
371
operation, as there is a separate plugin for getting a password

<refsect1 id="exit_status">

402
Since this program will be run as a keyscript, there is
403
little to no opportunity to pass command line arguments
404
to it. Therefore, it will <emphasis>also</emphasis>
405
read this file and use its contents as
406
whitespace-separated command line options. Also,
407
everything from a <quote>#</quote> character to the end
