What happens > then? The one thing I'm a little uneasy about is ignoring /etc/machine-id. Seems like distros *should* be creating it for us. And it would be convenient to have one source of machine identity rather than separate ones for different subsystems. Maybe we could use that if it exists, and fall back on generating our own only if it doesn't? (Well, where "use it" actually means take a hash of it, as explained in machine-id(5).) --b.
