IPS pkg support for Solaris

.. important::
    If you feel that Salt should be using this module to manage packages on a
    minion, and it is using a different module (or gives an error similar to
    *'pkg.install' is not available*), see :ref:`here
    <module-provider-override>`.

This module provides support for Solaris 11 new package management - IPS (Image Packaging System).
This is the default pkg module for Solaris 11 (and later).

If you want to use also other packaging module (e.g. pkgutil) together with IPS, you need to override the ``pkg`` provider
in sls for each package:

.. code-block:: yaml

    mypackage:
      pkg.installed:
        - provider: pkgutil

Or you can override it globally by setting the :conf_minion:`providers` parameter in your Minion config file like this:

.. code-block:: yaml

    providers:
      pkg: pkgutil

Or you can override it globally by setting the :conf_minion:`providers` parameter in your Minion config file like this:

.. code-block:: yaml

    providers:
      pkg: pkgutil

    newer version of ``pkg://solaris/entire`` (which means that they can be
    upgraded only from the global zone). If ``pkg://solaris/entire`` is found
