I have an ArchLinux with systemd, and I've created my own service. The configuration service at /etc/systemd/system/myservice.service looks like this:

  [Unit]
  Description=My Daemon

  [Service]
  ExecStart=/bin/myforegroundcmd

  [Install]
  WantedBy=multi-user.target

Now I want to have an environment variable set for the /bin/myforegroundcmd. How do I do that?

The recommended way to do this is to create a file /etc/sysconfig/myservice which contains your variables, and then load them with EnvironmentFile.

For complete details, see Fedora's documentation on how to write a systemd script.

I guess the sysconfig path is specific to Fedora but the question is about Arch Linux. The answer by paluh is more interesting I think – Ludovic Kuty Apr 27 at 8:49

http://0pointer.de/public/systemd-man/systemd.exec.html - you have two options (one already pointed by Michael):

Environment=

and

EnvironmentFile=

What about just putting the environment variable inside the myforegroundcmd script?

well, the whole point of having environment variables is to have them outside my binary, so that I can get different behavior in different installations... – lfagundes Aug 1 '12 at 20:38
