[Bug 1174272] Re: 'reboot now' reverting to maintenance mode

[Dimitri Pappas]

Welcome to Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-40-generic-pae i686)
root at host1:~# reboot now
The system is going down for reboot NOW!

Welcome to Ubuntu 13.04 (GNU/Linux 3.9.0-030900rc8-generic i686)
root at host2:~# reboot now
The system is going down to maintenance mode NOW!

(the same for shutdown)

It would seem that, sometimes, logic is not enough proof :)

Title:
  'reboot now' reverting to maintenance mode

Status in “upstart” package in Ubuntu:
  Invalid

Bug description:
  A forum thread has been opened first, describing the problem. For
  reference, that forum thread can be found here:
  http://ubuntuforums.org/showthread.php?t=2139160&p=12624806

  Problem is described below:

  When the command "reboot now" is issued:

  root at server:~# reboot now
  Broadcast message from root at server
  (/dev/pts/0) at 00:00 ...
  The system is going down to maintenance mode NOW!

  A few moments later.. SSHd is killed, but the box responds to pings
  (Inaccessible remotely unless a hard-reset is performed)

  * Asking all remaining processes to terminate...
  * Killing all remaining processes... [fail]
  * Will now switch to single-user mode
  Give root password for maintenance
  (or type Control-D to continue):

  Just "reboot", and it works fine
  root at server:~# reboot
  Broadcast message from root at server
  (/dev/pts/0) at 00:00 ...
  The system is going down for reboot NOW!

  Some distro's require a time / 'now' as an argument, and thus I became
  accustomed to performing my reboots in this way. Now it seems to be a
  potential trap that causes the machine not to reboot, which is
  especially painful if we're talking about a headless/hosted dedicated
  server. Even if ubuntu doesn't like 'reboot now' syntax, I still can't
  understand why "reboot now" should bring the box to console
  maintenance mode anyway - perhaps it should rather return an error, or
  syntax help
