I am not particularly surprised by this, and am pleased to learn that it is the case. However, as it remains the case that they are shipped in the same package as /bin/systemd, and as I gather (mostly from this thread, I think) that some of the ways they are expected to be invoked probably rely on having systemd-the-daemon running, this does not entirely obviate my concerns related to needing to have systemd-the-package's daemons present in order to gain access to these facilities. If these two programs were to be split out into one or more separate packages (which IMO would probably also be a good idea for some of the other binaries shipped in systemd-the-package, but that's another discussion), and those packages did not depend on the systemd package, that would greatly improve the situation from my perspective. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
