Phoronix: systemd OOMD Maturing Nicely, Adds Support For User Services

Systemd-oomd as the out-of-memory daemon originally developed by Facebook has been maturing nicely since being merged last year and then its most notable deployment to date has been with Fedora 34's debut earlier this year. Anita Zhang of Facebook provided an update today on the systemd-oomd effort...

As far as I know, systemd-oomd does not share code with Facebook's oomd, systemd just decided to copy the algorithm from their writeup wholesale and write their own.

Hell, Facebook's oomd is in C++, and (like, AFAIK, all of systemd) systemd-oomd is C.

Is this an issue?

I mention it because the article opens with "Systemd-oomd as the out-of-memory daemon originally developed by Facebook", which is not really accurate.

Can't believe no one complained about having a whole social network inside the init system yet...

With systemd's pace of annoying feature creep, give it time.

It is accurate on the lineage. Facebook developed it internally, then made it open source. Then they put up a pull request to merge it in systemd

https://github.com/systemd/systemd/pull/15206

Now they continue to make improvements to it within systemd.

Not true. Facebook put up that PR to implement the same functionality in systemd. "systemd" didn't decide to copy anything. It is not capable of such things

systemd-oomd blows away the gnome-shell desktop session

Is this OK?

systemd-oomd kills the whole session if it's started from console https://bugzilla.redhat.com/show_bug.cgi?id=1933494

Ah, neat, thanks!

I give it 5 years or less before the systemd roadmap is being "informed" by systemd-hal9000.
