systemd service is available for review at: kartik@opusmt.eqiad.wmflabs:/home/kartik/opusmt.service

The file should be in some stable location in case the cloud machine goes poof.

What's ENV_DIR? Do not use /bin/sh. You can use EnvironmentFile= I think.

Agree. I'll submit pull request to upstream after we get it working :)

ENV_DIR is used for Python virtual environment. Used EnvironmentFile= now to tell service to use it from there.

Unused language models are removed from configuration file, so instance will be faster now.

@Nikerabbit I've moved script as systemd service now, but not yet enabled by default. opusmt still running as script in my user screen :) I'll ping you again once it is ready.

Still breaks service startup, so moved back to 'In progress'.

OpusMT now runs with basic (bit hacky, but better than screen session!) service on cloud instance:

kartik@opusmt:~$ sudo service opusmt status
