-# == Define: elasticsearch::service::systemd
-#
-# This define exists to coordinate all service management related actions,
-# functionality and logical units in a central place.
-#
-# <b>Note:</b> "service" is the Puppet term and type for background processes
-# in general and is used in a platform-independent way. E.g. "service" means
-# "daemon" in relation to Unix-like systems.
-#
-#
-# === Parameters
-#
-# [*ensure*]
-# String. Controls if the managed resources shall be <tt>present</tt> or
-# <tt>absent</tt>. If set to <tt>absent</tt>:
-# * The managed software packages are being uninstalled.
-# * Any traces of the packages will be purged as good as possible. This may
-# include existing configuration files. The exact behavior is provider
-# dependent. Q.v.:
-# * Puppet type reference: {package, "purgeable"}[http://j.mp/xbxmNP]
-# * {Puppet's package provider source code}[http://j.mp/wtVCaL]
-# * System modifications (if any) will be reverted as good as possible
-# (e.g. removal of created users, services, changed log settings, ...).
-# * This is thus destructive and should be used with care.
-# Defaults to <tt>present</tt>.
-#
-# [*status*]
-# String to define the status of the service. Possible values:
-# * <tt>enabled</tt>: Service is running and will be started at boot time.
-# * <tt>disabled</tt>: Service is stopped and will not be started at boot
-# time.
-# * <tt>running</tt>: Service is running but will not be started at boot time.
-# You can use this to start a service on the first Puppet run instead of
-# the system startup.
-# * <tt>unmanaged</tt>: Service will not be started at boot time and Puppet
-# does not care whether the service is running or not. For example, this may
-# be useful if a cluster management software is used to decide when to start
-# the service plus assuring it is running on the desired node.
-# Defaults to <tt>enabled</tt>. The singular form ("service") is used for the
-# sake of convenience. Of course, the defined status affects all services if
-# more than one is managed (see <tt>service.pp</tt> to check if this is the
-# case).
-#
-# [*init_defaults*]
-# Defaults file content in hash representation
-#
-# [*init_defaults_file*]
-# Defaults file as puppet resource
-#
-# [*init_template*]
-# Service file as a template
-#
-# === Authors
