# The systemd services dictionary is a set of services that will be created. The dictionary
#  can contain the following options:
#  `service_name` -- (required) used to define the name of the service. This is typically the name of the executable.
#  `service_type` -- (optional) Set the service type, default is "simple".
#  `execstarts` -- (required) Set the program to start, when the service is simple the list has a max length of 1.
#  `execstops` -- (optional) Set the program to stop, when the service is simple the list has a max length of 1.
#  `after_targets` -- (optional) Start the service after this list of dependency units.
#  `partof` -- (optional) Set the systemd "partof" directive. This ties a service unit to another.
#  `config_overrides` -- (optional) This allows any section or key=value pair to be set within the systemd unit file.
#  `program_sandboxing` -- (optional) Case sensitive Key=Value pairs for service Sandboxing
#  `program_accounting` -- (optional) Case sensitive Key=Value pairs for service Accounting
#  `enabled` -- (optional) Set the enabled state of the service.
#  `state` -- (optional) Set the running state of the service.
#  `environment` -- (optional) set additional environment settings, this option is a hash of strings.
#  `environment_file` -- (optional) set additional environment settings through a given file. this option is a string.
#  `dynamic_user` -- (optional) Dynamically set a UNIX user and group when the unit is started; only works if systemd >= 235.
#  `template_arguments` -- (optional) List of arguments that would be enabled/started in case service is a template.
#                          For that to work properly, service_name should end with `@`, ie `dhcpcd@`
#                          Systemd service template documentation can be found by the link:
#                          https://www.freedesktop.org/software/systemd/man/systemd.service.html#Service%20Templates
#  `state_directory` -- (optional) Relative path the state directory; only works if systemd >= 235.
#  `systemd_overrides` -- (optional) Dictionary that may contain custom structure in config_overrides format that
#                         will be used to generate systemd overrides in /etc/systemd/system/service_name.service.d/overrides.conf
#  `systemd_overrides_only` -- (optional) Boolean variable, when True no service_name.service will be generated and role
#                              will place only overrides for the existing service.
#  `systemd_run_dir` -- (optional) Run directory that will be used for service runtime. Service slice or name is added to the path
#  `systemd_lock_dir` -- (optional) Lock directory that will be used for service runtime. Service slice or name is added to the path
#  `load` -- (optional) Boolean to set if the service is loaded. Socket activated services with '@' may not need to be loaded.
#  `standard_output` -- (optional) Set the stdout of the service to go to a non default destination, such as 'socket'

# Under the service dictionary the "sockets" key can be added, which may contain list of the sockets
#  for the given service_name. Each socket in the lsit may have following structure:
#  `socket_name` -- (required) Name of created socket
#  `after_targets` -- (optional) Start the socket after this list of dependency units.
#  `before_targets` -- (optional) Start the socket before this list of dependency units.
#  `bind_targets` -- (optional) Bind the socket to this dependency unit.
#  `enabled` -- (optional) Set the enabled state of the socket.
#  `options` -- (optional) Additional options, like `ListenStream` or other. Specifying ListenStream in
#               the options will suppress the default 'Service' field in [Socket]. 
#  `state` -- (optional) Set the running state of the socket.

# Under the service dictionary the "timer" key can be added which will enable a given service
#  as a timer (Legacy cron job).
#  `options` -- (optional) This allows any section or key=value pair to be set within the systemd timer file.
#  `cron_minute` -- (optional) This allows for "on calendar configuration" (AKA CRON) for the minute segment.
#  `cron_hour` -- (optional) This allows for "on calendar configuration" (AKA CRON) for the hour segment.
#  `cron_day` -- (optional) This allows for "on calendar configuration" (AKA CRON) for the day segment.
#  `cron_weekday` -- (optional) This allows for "on calendar configuration" (AKA CRON) for the weekday segment.
#  `cron_month` -- (optional) This allows for "on calendar configuration" (AKA CRON) for the month segment.
