100
107
All <command>&COMMANDNAME;</command> does is prompt for a
101
password and output any given password to standard output.
104
This program is not very useful on its own. This program is
105
really meant to run as a plugin in the <application
106
>Mandos</application> client-side system, where it is used as a
107
fallback and alternative to retrieving passwords from a
108
<application >Mandos</application> server.

109
is not very useful on its own. This program is really meant to
110
run as a plugin in the <application>Mandos</application>
111
client-side system, where it is used as a fallback and

116
This program is little more than a <citerefentry><refentrytitle

118
wrapper, although actual use of that function is not guaranteed
117
This program tries to detect if a Plymouth daemon
118
(<citerefentry><refentrytitle
119
>plymouthd</refentrytitle><manvolnum>8</manvolnum></citerefentry>)
120
is running, by looking for a
121
<filename>/run/plymouth/pid</filename> file or a process named
122
<quote><literal>plymouthd</literal></quote>. If it is detected,
123
this process will immediately exit without doing anything.

parsing kernel arguments and

222
initial RAM disk environment), which in turn will have been
223
created when the initial RAM disk image was created by

226
extracting the information of the root file system from

<filename >/etc/crypttab</filename>.
