2025-10 monthly summary for the yuwata/systemd repository focused on hardening OSC event reporting in containerized and non-systemd environments. Delivered a robust fix to guard machine-id reporting by conditionally including /etc/machine-id in OSC events only when the file exists, preventing errors when systemd isn’t fully running (e.g., OCI containers). The change drops the machine-id OSC event field if /etc/machine-id doesn’t exist, as committed in 0fe45b98dd737da86fcbb703809ebf2163c397f3 ("Drop `machine-id` OSC event field if /etc/machine-id doesn't exist").
