Right now, the reboot warning messages only makes a vague reference to "this system":
vyos@vyos:~$ reboot Are you sure you want to reboot this system? [y/N]
I suppose for extra safety, we could make it more specific, like "Are you sure you want to reboot this system (core-01.north.example.com)?" to give operators an extra reminder of what exact system they are about to reboot.
