I have this systemd unit file and my attempt was to convert the existing init.d script to a systemd unit file. I am having trouble declaring the config file that should be used as declared in the init.d script.
Here is the init.d script:
And here is my attempt so far of the systemd unit file:
Hi,
I want to use a config file as the base file and parse over the values of country and city parameters in the config file and generate separate config files as explained below.
I will be using the config file as mentioned below:

I was testing Fedora 16 mostly to check the new features. One thing that caught my eye as a systems admin is the systemd which is incorporated in Fedora for quite a while now.
From the first look of it, this appears more close to Solaris's SMF. With parallelization capabilities, advanced... (0 Replies)

systemd.environment-generator
SYSTEMD.ENVIRONMENT-GENERATOR(7) systemd.environment-generator SYSTEMD.ENVIRONMENT-GENERATOR(7)NAME
systemd.environment-generator - systemd environment file generators
SYNOPSIS
/lib/systemd/system-environment-generators/some-generator
/usr/lib/systemd/user-environment-generators/some-generator
/run/systemd/system-environment-generators/*
/etc/systemd/system-environment-generators/*

DESCRIPTION
Generators are small executables that live in /lib/systemd/system-environment-generators/ and other directories listed above. systemd(1)
will execute those binaries very early at the startup of each manager and at configuration reload time, before running the generators
described in systemd.generator(7) and before starting any units. Environment generators can override the environment that the manager
exports to services and other processes.
Generators are loaded from a set of paths determined during compilation, as listed above. System and user environment generators are loaded
from directories with names ending in system-environment-generators/ and user-environment-generators/, respectively. Generators found in
directories listed earlier override the ones with the same name in directories lower in the list. A symlink to /dev/null or an empty file
can be used to mask a generator, thereby preventing it from running. Please note that the order of the two directories with the highest
priority is reversed with respect to the unit load path, and generators in /run overwrite those in /etc.
After installing new generators or updating the configuration, systemctl daemon-reload may be executed. This will re-run all generators,
updating environment configuration. It will be used for any services that are started subsequently.
Environment file generators are executed similarly to unit file generators described in systemd.generator(7), with the following
differences:
o Generators are executed sequentially in the alphanumerical order of the final component of their name. The output of each generator
output is immediately parsed and used to update the environment for generators that run after that. Thus, later generators can use
and/or modify the output of earlier generators.
o Generators are run by every manager instance, their output can be different for each user.
It is recommended to use numerical prefixes for generator names to simplify ordering.
EXAMPLES
Example 1. A simple generator that extends an environment variable if a directory exists in the file system
# 50-xdg-data-dirs.sh
#!/bin/bash
# set the default value
XDG_DATA_DIRS="${XDG_DATA_DIRS:-/usr/local/share/:/usr/share}"
# add a directory if it exists
if [[ -d /opt/foo/share ]]; then
XDG_DATA_DIRS=/opt/foo/share:${XDG_DATA_DIRS}
fi
# write our output
echo XDG_DATA_DIRS=$XDG_DATA_DIRS
Example 2. A more complicated generator which reads existing configuration and mutates one variable
# 90-rearrange-path.py
#!/usr/bin/env python3
"""
Proof-of-concept systemd environment generator that makes sure that bin dirs
are always after matching sbin dirs in the path.
(Changes /sbin:/bin:/foo/bar to /bin:/sbin:/foo/bar.)
This generator shows how to override the configuration possibly created by
earlier generators. It would be easier to write in bash, but let's have it
in Python just to prove that we can, and to serve as a template for more
interesting generators.
