So, at boot time, the Mandos client will ask for its encrypted
134
data over the network, decrypt the data to get the password, use
135
the password to decrypt the root file system, and the client can
136
then continue booting.

More advanced startup systems like <citerefentry><refentrytitle
392
>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
393
already have their own plugin-like mechanisms for allowing
394
multiple agents to independently retrieve a password and deliver
395
it to the subsystem requesting a password to unlock the root
396
file system. On these systems, it would make no sense to run
397
<citerefentry><refentrytitle>plugin-runner</refentrytitle
398
><manvolnum>8mandos</manvolnum></citerefentry>, the plugins of
399
which would largely duplicate the work of (and conflict with)
400
the existing systems prompting for passwords.

As for <citerefentry><refentrytitle>systemd</refentrytitle

<citerefentry><refentrytitle>password-agent</refentrytitle
409
><manvolnum>8mandos</manvolnum></citerefentry> program, which
410
is run instead of <citerefentry><refentrytitle
411
>plugin-runner</refentrytitle><manvolnum>8mandos</manvolnum
412
></citerefentry> when <citerefentry><refentrytitle
413

414
is used during system startup.
