+ <listitem><para>Switches to a
+ different root directory and executes
+ a new system manager process below
+ it. This is intended for usage in
+ initial RAM disks ("initrd"), and will
+ transition from the initrd's system
+ manager process (a.k.a "init" process)
+ to the main system manager
+ process. Takes two arguments: the
+ directory to make the new root
+ directory, and the path to the new
+ system manager binary below it to
+ execute as PID 1. If the latter is
+ ommitted or the empty string, a
+ systemd binary will automatically be
+ searched for and used as init. If the
+ system manager path is ommitted or
+ equal the empty string the state of
+ the initrd's system manager process is
+ passed to the main system manager,
+ which allows later introspection of the
+ state of the services involved in the
+ initrd boot.</para></listitem>
