Subject: [PATCH] Set machine-id to uninitialized
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An empty `/etc/machine-id` file does _not_ trigger systemd's "first
boot" logic.  This means with `ConditionFirstBoot=true` will not run,
and the unit preset policy will not be applied.  To ensure a first boot
behaves the way we want, we need to pre-populate the `/etc/machine-id`
file with the string `uninitialized\n`, per _machine-id(5)_ § _First
Boot Semantics_.
