It would be wonderful to have Debian ship a systemd user service file for
devilspie2. I've searched the internet a bit and know a bit about systemd, but
don't know the exact configurations for said service file. My current attempts
are failing. If I get it to work, I'll follow-up to this bug report.

It'd be great to be able to:

systemctl --user enable devilspie2
systemctl --user start devilspie2

and have it work out of the box.

Thanks for hearing this bug report and considering it.

Cheers!
