I think all systemd related stuff should finally live in meta-systemd
to make other layers independent of using systemd or not. I separated
two types of metadata:
1. Recipes/classes only found in this layer - like systemd itself (or
later e.g dietsplash designed to work only with systemd)
2. Extends of other layers (currently meta-oe/meta-gnome/meta-efl -
and in the future e.g oe-core/meta-ti/meta-angstrom...). For this an
additional directory hierarchy was added to give a better chance to
BBMASK. E.g a user wants to use systemd but does not want meta-ti. The
idea of only having bbappends was to force only appending not
overriding recipes of other layers.
