+ <title>Systemd in the Initrd</title>
+ <para>If the initrd creation tool used the services provided
+ by systemd, the default target in the initrd is the
+ initrd-fs.target. The process is the same as above until the basic.target is reached.
+ Systemd now continues to the initrd.target. If the root device could be mounted
+ on /sysroot, the sysroot.mount unit is active and the initrd-root-fs.target is reached.
+ initrd-parse-etc.service scans /sysroot/etc/fstab for the /usr mountpoint and for entries
+ marked with the <emphasis>x-initrd.mount</emphasis> option set. If these mountpoint are
+ mounted in /sysroot, the initrd-fs.target is reached.
+ The initrd-cleanup.service isolates to the initrd-switch-root.target,
+ where cleanup services can run. At the very last end
+ initrd-switch-root.service is activated, which will cause
+ the system to switch root to /sysroot.
