[OE-core] [PATCH 0/7] systemd patches

[Jonas Bonn]

These patches make some modifications to systemd with the long-term goal
of being able to run OE in systemd's "stateless" configuration.
"Stateless" boils down to building an image with empty /etc and /var
directories so that volatile (tmpfs) filesystems can be mounted there;
this requires that the system subsequently be able to populate these
directories dynamically, which systemd mostly takes care of if things
are done right.

In these patches:
i)    Don't include machine-id in writable images so that systemd can run
its first-boot machinery
ii)   Move systemd configuration files out of /etc
iii)  Allow systemd to dynamically enable services and populate
/etc/systemd/system via the presets mechanism

There's a long way to go to get to a working "stateless" configuration.
Getting to a "volatile" system (just empty /var) should be easier and
I'll post patches moving things in that direction shortly.

Jonas Bonn (7):
  systemd: do not create machine-id
  systemd-conf: simplify creation of configuration
  systemd: move additional conffiles to systemd-conf
  systemd: create preset files instead of installing in image
  systemd-systemctl-native: simplify and support preset-all
  rootfs-postcommands: call preset-all for read-only-rootfs
  systemd: do not pre-enable services, rely on presets
