Harald Seiler 3023f2fead core: keep machine-id transient until first boot completes ... Currently, a loss of power after the machine-id was written but before all units with ConditionFirstBoot=yes ran would lead to the next boot finding a valid machine-id, thus not being marked first boot and not re-running these units. To make the first boot mechanism more robust, instead of writing /etc/machine-id very early, fill it with a marker value "uninitialized" and overmount it with a transiently provisioned machine-id. Then, after the first boots completes (when systemd-machine-id-commit.service runs), write the real machine-id to disk. This mechanism is of course only invoked on first boot. If a first boot is not detected, the machine-id is handled as previously. Fixes: #4511		2020-10-19 16:28:22 +02:00
