and some other directives documented on the same page.
I had completely forgotten about these directives! It's things like this that make me glad systemd is a choice, honestly.
SystemD did not invent cgroups. Not only is it possible to use cgroups without systemd it is often easier for small cases and binaries can call cgroups themselves for any child processes they create.
The timing of these systems releasing does not equate to causation here. Google themselves (creators of cgroups) do not even use systemd on their own hypervisors which leverage cgroups heavily.
Nobody said they did. You’re putting words in my mouth. The ease of use with 2-3 directives in a way that just works is what they brought to the table.
This is an interesting claim, mind throwing some pointers?
