The sysconfig command is used to query or modify the kernel
    subsystem configuration. You use this command to reconfigure
    subsystems already in the kernel and to ask for information about
    (query) subsystems in the kernel.

    A subset of kernel subsystems can be managed using the sysconfig
    command. This command allows you to modify the value of
    subsystem attributes, so long as the subsystem supports run-time
    modifications.

    The first argument to the sysconfig command is the subsystem-
    name argument. The subsystem-name argument names the subsystem
    on which you want to perform the operation specified by one of
    the required flags, such as the -q (query attributes) flag. The
    subsystem-name argument is required for all flags except -s and
    -m. If you omit the subsystem name when you use one of these
    flags, the sysconfig command displayed information about all
    loaded subsystems.

    The attribute-list argument lists attribute names and, depending
    on the operation, attribute values. For reconfigure operations
    (-r), the attribute-list argument has the following format:

      attribute1=value1 attribute2=value2...

    You cannot include spaces between the attribute name, the equal
    sign (=), and the value.

    For query attribute (-q) operations, the attribute-list has the
    following format:

      attribute1 attribute2...

    The attribute-list argument is required when you use the -r flag
    and is optional with the -q flag. Any attribute-list specifies
    with other flags is ignored by the sysconfig command.

    If you want to modify the value of a subsystem attribute, you
    use the -r (reconfigure) flag. When you use the -r flag, the
    sysconfig command modifies the named attributes by storing
    the value you specify in them. The modifications take effect
    immediately. Changes are only to the running system.

    To get information about subsystem attributes, use either the
    -q flag or the -Q flag. You can specify an attribute list with
    both these flags. When you use the -q flag, the sysconfig command
    reads the value of attributes from the kernel and displays those
    values on your local display. When you use the -Q flag, the
    sysconfig command displays the following information about either
    each attribute in the subsystem or, if specified, each attribute
    in the attribute-list:

    o  Attribute datatype.

    o  Operations supported by the attribute. This information
       indicates, for example, whether you can reconfigure the
       attribute using the sysconfig -r command.

    o  Minimum and maximum allowed attribute value.

    To get information about the state of subsystems, use the -
    s flag. This flag provides a list of the subsystems that are
    currently loaded and configured into the kernel. If you specify
    subsystem-name, the command displays information about the state
    of that subsystem. Each subsystem can have one of three states:

    o  Loaded and configured (available for use)

    o  Loaded and unconfigured (not available for use, but still
       loaded)

       This state applies only to static subsystems, which can be
       unconfigured but cannot be unloaded.
