Boot ID is *always* generated by the kernel on every boot and not stored anywhere, only available from sysctl. Machine ID is usually static -- generated once after installation, and stored in /etc/machine-id. It only changes on diskless systems or if /etc is unwritable for some other reason. (systemd can get the machine ID from /sys/class/dmi/id/product_uuid, but only does so on qemu-kvm VMs.) -- Mantas Mikulėnas <graw...@gmail.com> _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
