However, I think the main "systemd" executable belongs in /bin. I read (b) as a subdivision of the category established by the previous sentence: "Utilities used for system administration (and other root-only commands) are stored in /sbin, /usr/sbin, and /usr/local/sbin." systemd is not (going to be) root-only, hence it doesn't go in */sbin. The right comparison would be to /bin/dbus-daemon. -- Matt -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
