If your desktop doesn't segregate apps and services into cgroups,
systemd-oomd will kill the entire desktop whenever anything uses too
much memory, because the desktop is going to be running in the same
cgroup as the apps that it launches. So I think desktop spins (other
than KDE) ought to opt out of this. It should be good for all Fedora
editions, though (including Workstation, Server, Atomic, CoreOS), and
also for KDE spin.
How will this work on headless systems like Fedora Server, Atomic, and CoreOS? Will it be
expected that users manually create their own cgroups?
