NAME
       cmpt_tune - query, enable, or disable compartmentalization feature

SYNOPSIS

       boot_image]

       boot_image]

DESCRIPTION
       queries,  enables,  or disables the compartmentalization feature.  Compartmentalization is not a dynamic feature; enabling or disabling the
       feature requires a reboot.  If you make a change and do not specify the flag, reports a reboot reminder message.  If no options are  speci-
       fied, the option is assumed.

       If  no  compartments  have  been defined when compartmentalization is enabled, the network interfaces currently installed on the system are
       assigned to a new compartment and the administrator is given the opportunity to reassign these interfaces (see getrules(1M)).

       The system initially boots into a predefined compartment, A process in the compartment can access all  objects  (that  is,  all	processes,
       files,  IPC  objects,  etc.,  are accessible from the compartment).  See compartments(5) for more information.  Using the command (see set-
       filexsec(1M)), an administrator can set specific binaries to start automatically in other compartments; that is, when  a  process  executes
       the binary, it may find its compartment modified as a side-effect.  This concept is similar to a setuid binary changing a process's euid.

       When  the or option is specified without the option, the current running configuration is modified.  If or is specified with the option and
       boot_image does not exist, it is created as though the administrator ran the following command:

       In any case, boot_image is marked for use on the next boot.

   Options
       The command recognizes the following options:

	      Disables compartments.

	      Enables compartments.

	      Prints a help message.

	      Makes changes to or queries the specified
			boot_image.  If this option is not specified, defaults to If no other options are specified, the option is assumed.

	      Queries the current state of compartments.

	      Queries the state of compartments after the next reboot.

	      Reboots after making changes.
			You can only use this option with the or options.

	      Sets silent mode.
			Only the exit status is set.

RETURN VALUE
       returns the following values:

	      When querying, the compartmentalization feature is enabled.
		     When making changes, the changes are successfully applied.

	      An option processing error occurred.
		     When querying, the compartmentalization feature is disabled.  When making changes, and is specified,  the	reboot	option	is
		     ignored (for example, to allow for editing of compartment configuration files).

	      When querying, the kernel configuration specified does not exist
		     or has no support for compartmentalization.

WARNINGS
       A  network  interface  that is not assigned to any compartment cannot be accessed by any process and effectively cannot be used.  Assign at
       least one network interface to a compartment so that network communications can function.

       If the or option is used in conjunction with the option, any prior changes pending to the current configuration are lost.

       If the compartments feature is enabled on a kernel configuration that does not reflect  the  required  patch  levels  (for  example,  patch
       PHKL_32798 is missing), the system may not boot properly or may not have network connectivity.
