<para>This target usually does not pull in any non-target units
directly, but rather does so indirectly via other early boot targets.
It is instead meant as a synchronization point for late boot
services. Refer to

for details on the targets involved.

<para>A special target unit covering early boot-up
scripts.</para>
<para>This target pulls in the services required for system
initialization. System services pulled in by this target should
declare <varname>DefaultDependencies=no</varname> and specify
all their dependencies manually, including access to anything
more than a read only root filesystem. For details on the
dependencies of this target, refer to
