You are right /etc/machine-id is different for every boot as we have a read-only filesystem. /etc/machine-id is being mounted to /run/machine-id by systemd-machine-id-setup. I have a persistent data partition, how do I mount it into this? I tried --root /data but this didn't work. Should I disable the /lib/systemd/system/systemd-machine-id-commit.service and create /etc/machine-id myself using something like the MAC address and some random numbers? Cheers, Martin.
