/etc/machine-id the same on every installation

[rhuss]

First of all apologies if this is the wrong place for opening this issue (feel free to move it around)

I hit the following issue that on all my pi installations with Hypriot 1.4.0 I get the same /etc/machine-id. This causes issues when running an overlay network which uses this ID to calculate a virtual mac address.

Actually the same id 9989a26f06984d6dbadc01770f018e3b remains even after a reflash. And even stranger, when removing this file and calling systemd-machine-id-setup it recreates the id file with again this value. Looks for me a bit like an issue with how systemd extracts an UUID (it says "Initializing machine ID from D-Bus machine ID.", so maybe that's a constant ?)

The solution for now is that after flashing I call a

dbus-uuidgen > /etc/machine-id

or when using ansible with an ad-hoc ansible command.

ansible pis -u pirate -k -i hosts --become -m shell --args "dbus-uuidgen > /etc/machine-id"

Maybe one could add something similar to the initial startup of a freshly flashed Hypriot ?

Same as #143, but thanks for more details.

thanks and sorry for not checking the other issues first.
