At first boot, systemd will create the /etc/systemd/system directory
from service preset files.  As such, for a normal, writable /etc
(writable rootfs), there is no need to set up this directory at image
creation time.

This patch changes the systemd machinery to create preset files and to
rely on systemd to do the service enablement.

This breaks the read-only-rootfs case; there's a fix for this in a
follow-up patch.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
