Subject: [PATCH] build-sys: don't hard-code binary paths in initrd-*.service
Instead use @bindir@ for udevadm and @rootbindir@ for systemctl.

From 700e07ffd53083114e91bb4ba646ed26d0463f67 Mon Sep 17 00:00:00 2001
From: Harald Hoyer <harald@redhat.com>
Date: Mon, 4 Mar 2013 19:01:05 +0100
Subject: [PATCH] add initrd-fs.target and root-fs.target
Instead of using local-fs*.target in the initrd, use root-fs.target for
sysroot.mount and initrd-fs.target for /sysroot/usr and friends.
Using local-fs.target would mean to carry over the activated
local-fs.target to the isolated initrd-switch-root.target and thus in
the real root. Having local-fs.target already active after
deserialization causes ordering problems with the real root services and
targets.
We better isolate to targets for initrd-switch-root.target, which are
only available in the initrd.

Subject: [PATCH] main: don't mount /sys, /dev and friends when we run with PID
!= 1
Back from old times when we developed systemd on non-systemd hosts we
still mounted the missing directories such as the cgroup stuff even when
running with a PID != 1. There's no point for that anymore, so let's
just do that if we are actually PID 1, and never otherwise.

Subject: [PATCH] Make initrd.target the default target in the initrd
First, rename root-fs.target to initrd-root-fs.target to clarify its usage.
Mount units with "x-initrd-rootfs.mount" are now ordered before
initrd-root-fs.target. As we sometimes construct /sysroot mounts in
/etc/fstab in the initrd, we want these to be mounted before the
initrd-root-fs.target is active.
initrd.target can be the default target in the initrd.
(normal startup)

+ <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.
