<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

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
