Fwiw, I can reproduce this particular bug under Fedora: Just remove the /usr/lib/systemd/system/local-fs.target.wants/tmp.mount symlink, reboot, login on tty2, notice how tmp.mount is not active (mounted), although there are various services active with PrivateTmp=true. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? _______________________________________________ systemd-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/systemd-devel
