104
This program takes no options.
127
This program is commonly not invoked from the command line; it
128
is normally started by the <application>Mandos</application>
129
plugin runner, see <citerefentry><refentrytitle
130
>plugin-runner</refentrytitle><manvolnum>8mandos</manvolnum>
131
</citerefentry>. Any command line options this program accepts
132
are therefore normally provided by the plugin runner, and not
138
<term><option>--prompt=<replaceable
139
>PROMPT</replaceable></option></term>
142
The password prompt. Note that using this option will
143
make this program ignore the <envar>cryptsource</envar>
144
and <envar>crypttarget</envar> environment variables.
150
<term><option>--debug</option></term>
153
Enable debug mode. This will enable a lot of output to
154
standard error about what the program is doing. The
155
program will still perform all other functions normally.
161
<term><option>--help</option></term>
162
<term><option>-?</option></term>
165
Gives a help message about options and their meanings.
171
<term><option>--usage</option></term>
174
Gives a short usage message.
180
<term><option>--version</option></term>
181
<term><option>-V</option></term>
184
Prints the program version.

218
<citerefentry><refentrytitle>plugin-runner</refentrytitle>

<manvolnum>8mandos</manvolnum></citerefentry>, which will
136
normally have inherited them from
137
<filename>/scripts/local-top/cryptroot</filename> in the
138
initial <acronym>RAM</acronym> disk environment, which will
139
have set them from parsing kernel arguments and
140
<filename>/conf/conf.d/cryptroot</filename> (also in the
141
initial RAM disk environment), which in turn will have been
142
created when the initial RAM disk image was created by
144
>/usr/share/initramfs-tools/hooks/cryptroot</filename>, by
145
extracting the information of the root file system from
146
<filename >/etc/crypttab</filename>.
219
<manvolnum>8mandos</manvolnum></citerefentry>, which might
220
have in turn inherited them from its calling process.

This behavior is meant to exactly mirror the behavior of
150
<command>askpass</command>, the default password prompter.

from initramfs-tools.
