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

[Margarita Manterola]

Not taking an argument is one thing, failing to reboot with an error
message would then be fine.

A completely different thing is showing unexpected behavior, by shutting
everything down and leaving an open root console.

This is the current manual page in trusty:

----
SYNOPSIS
       reboot [OPTION]...  [REBOOTCOMMAND]

       halt [OPTION]...

       poweroff [OPTION]...

DESCRIPTION
       These programs allow a system administrator to reboot, halt or poweroff the system.

       When  called  with  --force  or  when in runlevel 0 or 6, this tool invokes the reboot(2) system call
       itself (with REBOOTCOMMAND argument passed) and directly reboots the system.  Otherwise  this  simply
       invokes the shutdown(8) tool with the appropriate arguments without passing REBOOTCOMMAND argument.

       Before invoking reboot(2), a shutdown time record is first written to /var/log/wtmp
----

It says that it will simply invoke shutdown *without passing
REBOOTCOMMAND*.  If the command actually did that, then this bug
wouldn't exist.

So, yes, it IS a bug.

Title:
  'reboot now' reverting to maintenance mode

Status in “upstart” package in Ubuntu:
  Fix Released

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
