So, at boot time, the Mandos client will ask for its encrypted

data over the network, decrypt it to get the password, use it to
135
decrypt the root file, and continue booting.

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

the existing systems prompting for passwords.

run instead of <citerefentry><refentrytitle

>plugin-runner</refentrytitle><manvolnum>8mandos</manvolnum

></citerefentry> when <citerefentry><refentrytitle
414
>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
415
is used during system startup.
