Define "automatically" and "services" first ;-) Normally you just set it in the systemd's unit file for each daemon you want to adjust. So for some definitions of the above the answer is yes. (OOMScoreAdjust in https://www.freedesktop.org/software/systemd/man/systemd.exe...)

Personally, I use one tool for both FreeBSD and Linux. Picking up the (imported) rc.conf variable for a service is a mere matter of

    oom-kill-protect fromenv

And the conversion from something like OOMScoreAdjust is quite straightforward. A PostgreSQL systemd unit file that read OOMScoreAdjust=-625 becomes a run program that contains

    oom-kill-protect -- -625

Cool, thanks for sharing. I would hate to have to muck around in /proc manually to set this.
