I agree. I don't want to add a debconf prompt for this. Aside from the overhead, this just shifts the problem to the user. >> BTW, *why* does systemd needs this file to be constant?

Fwiw, I wouldn't mind to unconditionally rm the file on purge in postrm (we do the same for dbus wrt /var/lib/dbus/machine-id) given that no other package relies on the file. That said, I don't know if any other package relies on /etc/machine-id. I do know that dbus makes use of it but I dunno all the details regarding the /var/lib/dbus/machine-id fallback Say we first install systemd, which generates /etc/machine-id, then later dbus. Will in this case a /var/lib/dbus/machine-id file be created or will dbus use /etc/machine-id? In this case we can't remove /etc/machine-id again, as it would break dbus, unless dbus would on-the-fly generate a /var/lib/dbus/machine-id if no /etc/machine-id is available. Maybe Simon knows more. Regards, Michael -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
