5ae89ef347 core/systemctl: when switching root default to /sysroot/
We hardcode the path the initrd uses to prepare the final mount point at
so many places, let's also imply it in "systemctl switch-root" if not
specified.

This adds the fallback both to systemctl and to PID 1 (this is because
both to — different – checks on the path).

5b5ec138c6 units: make sure that initrd-switch-root.service pulls in .target
Normally we queue initrd-switch-root.target/isolate, which pulls in the
service via Wants= in the .target unit file. But if the service is instead
started directly, there may be nothing pulling in the target. Let's make
sure that the reference exists.

9810e41942 units: reorder/split unit dependency blocks
The block is reordered and split to have:
  1. description + documentation
  2. (optionally) conditions
  3. all the dependencies
I think it's easier to read the units this way.
Also, the Conflicts+Before is seperated out to separate lines.
The ordering dependency is "fake", because it could just as well be
After=, we are adding it to force ordering wrt. shutdown.target, and
it plays a different role than the other Before=, which are about a
real ordering on boot.

78490efca3 units: upgrade initrd check Conditions to Asserts
It's a bug if an initrd unit is run on the host. Hence let's upgrade the
conditions to asserts.

cdc6804b60 units: drop full paths for utilities in $PATH
This makes things a bit simpler and the build a bit faster, because we don't
have to rewrite files to do the trivial substitution. @rootbindir@ is always in
our internal $PATH that we use for non-absolute paths, so there should be no
functional change.

7b40ce553f build-sys: don't hard-code binary paths in initrd-*.service
Instead use @bindir@ for udevadm and @rootbindir@ for systemctl.

cf84347794 initrd: add unit files needed for basic systemd-in-initrd support
This will:
 * mount all configured filesystems (typically the rootfs on /sysroot)
 * reload the configuration to pick up anything from the mounted fs (typically
   /sysroot/etc/fstab)
 * mount any newly configured filesystems (typically /usr on /sysroot/usr, if
   applicable)
 * shut-down and clean-up any daemons running in the initramfs (typically udevd)
 * switch-root to /sysroot and start the real init

For an example of what files should be included in an initramfs based on this
