On this machine, I have lrwxrwxrwx 1 root root 35 2023-10-07 13:43:24 /etc/systemd/system/sockets.target.wants/dm-event.socket -> /lib/systemd/system/dm-event.socket while on another machine (installed more recently): lrwxrwxrwx 1 root root 39 2024-01-05 16:54:09 /etc/systemd/system/sockets.target.wants/dm-event.socket -> /usr/lib/systemd/system/dm-event.socket I suppose that the second one is the correct canonical path.
