Re: Fedora 34 Change: Enable systemd-oomd by default for all variants(System-Wide Change)

Each gnome-terminal tab runs in its own cgroup: │ │ │ ├─app-org.gnome.Terminal.slice │ │ │ │ ├─vte-spawn-1d1d5519-71d2-4035-929a-8a9ae5bc3822.scope │ │ │ │ │ ├─7848 bash │ │ │ │ │ └─7889 less /etc/hosts │ │ │ │ ├─vte-spawn-03fe4cc9-0400-4723-ac9b-e929b850ca02.scope │ │ │ │ │ ├─7892 bash │ │ │ │ │ ├─7927 systemd-cgls │ │ │ │ │ └─7928 less │ │ │ │ └─gnome-terminal-server.service │ │ │ │ └─7843 /usr/libexec/gnome-terminal-server Firefox does this too. WebKit doesn't, but it won't be hard to fix. Not sure about Chrome. Point is, apps have all the tools they need to use cgroups to ensure out-of-control subprocesses don't cause the main process to be killed, and our important default apps (Firefox and gnome-terminal) actually do this.
