    NAME
           lxc-autostart - start/stop/kill auto-started containers
    
    SYNOPSIS
           lxc-autostart
    [-k] [-L] [-r] [-s] [-a] [-A] [-g groups] [-t timeout]
    
    DESCRIPTION
           lxc-autostart processes containers with lxc.start.auto set. It lets the
           user start, shutdown, kill, restart containers in the right order,
           waiting the right time. Supports filtering by lxc.group or just run
           against all defined containers. It can also be used by external tools
           in list mode where no action will be performed and the list of affected
           containers (and if relevant, delays) will be shown.
    
           The [-r], [-s] and [-k] options specify the action to perform.  If none
           is specified, then the containers will be started.  [-a] and [-g] are
           used to specify which containers will be affected. By default only
           containers without a lxc.group set will be affected.  [-t TIMEOUT]
           specifies the maximum amount of time to wait for the container to
           complete the shutdown or reboot.
    
    OPTIONS
           -r,--reboot
    	      Request a reboot of the container.
    
           -s,--shutdown
    	      Request a clean shutdown. If a [-t timeout] greater than 0 is
    	      given and the container has not shut down within this period, it
    	      will be killed as with the [-k kill] option.
    
           -k,--kill
    	      Rather than requesting a clean shutdown of the container,
    	      explicitly kill all tasks in the container.
    
           -L,--list
    	      Rather than performing the action, just print the container name
    	      and wait delays until starting the next container.
    
           -t,--timeout TIMEOUT
    	      Wait TIMEOUT seconds before hard-stopping the container.
    
           -g,--group GROUP
    	      Comma separated list of groups to select (defaults to those
    	      without a lxc.group - the NULL group).  This option may be
    	      specified multiple times and the arguments concatenated. The
    	      NULL or empty group may be specified as a leading comma,
    	      trailing comma, embedded double comma, or empty argument where
    	      the NULL group should be processed.  Groups are processed in the
    	      order specified on the command line. Multiple invocations of the
    	      -g option may be freely intermixed with the comma separated
    	      lists and will be combined in specified order.
    
           -a,--all
    	      Ignore lxc.group and select all auto-started containers.
    
           -A,--ignore-auto
    	      Ignore the lxc.start.auto flag. Combined with -a, will select
    	      all containers on the system.
    
    AUTOSTART AND SYSTEM BOOT
           The lxc-autostart command is used as part of the LXC system service,
           when enabled to run on host system at bootup and at shutdown. It's used
           to select which containers to start in what order and how much to delay
           between each startup when the host system boots.
    
           Each container can be part of any number of groups or no group at all.
           Two groups are special. One is the NULL group, i.e. the container does
           not belong to any group. The other group is the "onboot" group.
    
           When the system boots with the LXC service enabled, it will first
           attempt to boot any containers with lxc.start.auto == 1 that is a
           member of the "onboot" group. The startup will be in order of
           lxc.start.order.	 If an lxc.start.delay has been specified, that delay
           will be honored before attempting to start the next container to give
           the current container time to begin initialization and reduce
           overloading the host system. After starting the members of the "onboot"
           group, the LXC system will proceed to boot containers with
           lxc.start.auto == 1 which are not members of any group (the NULL group)
           and proceed as with the onboot group.
    
    STARTUP GROUP EXAMPLES
           -g "onboot,"
    	      Start the "onboot" group first then the NULL group.
    
    	      This is the equivalent of: -g onboot -g "".
    
           -g "dns,web,,onboot"
    	      Starts the "dns" group first, the "web" group second, then the
    	      NULL group followed by the "onboot" group.
    
    	      This is the equivalent of: -g dns,web -g ,onboot or -g dns -g
    	      web -g "" -g onboot.
