"shutdown now" is supposed to switch to single-user mode (see bug 1065851).
"reboot now" is invalid - the shutdown command takes a time parameter (such as "now"), but the reboot command does not (see the man page). By specifying "reboot now" you are asking the system to reboot by running the "now" command, which is erroneous. ** Changed in: upstart (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174272 Title: 'reboot now' reverting to maintenance mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1174272/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
