I believe 'systemd-run' can do this now - launch any executable, creating a cgroup to contain it, and set various limits including memory usage. It may be worth a try.

`systemd-run` has been able to do this for a long time. I've used it to make sure a build doesn't require more than 4 GB per TU by running a non-parallel build under a strict memory limit. But, AFAIK, it does require using systemd as your init system (or, rather, cgroup manager), so perhaps systemd-run is the "just use systemd, man" solution alluded to here.

It sure can. It's as easy as:

systemd-run --user --property=MemoryMax=16G firefox

Note the part in the comment you replied to which says:

> never saw any useful docs for how to use them other than “just use systemd, man

You fulfilled the cliché beautifully, though, I’ve to admit.

(No, I don’t and won’t run systemd, period.)

You have to drive a nail in the wood. People say "just use a hammer, man". And you are like "never hammer, I will manage with this round rock somehow". It's your fault you ignore tools, so stop complaining.

Except systemd is not the hammer; systemd is a cheap asian version of a swiss army pocket knife, with too many functions bundled.

Like, Linux itself?
