It makes it possible to reliably track *all* processes started by a
particular service, no matter what convoluted techniques that service is
using to detach itself. Minor, I know, but useful...

But conversely, what's the *disadvantage* to using cgroups? If you're
thinking of all the resource management stuff, you should know that
systemd doesn't use that unless someone has configured a particular
service to use it. All it does by default is stick an identifying label
on the processes started from it, something with no overhead to speak

Have you read Lennart's blog posts? While there's certainly an element
of "information overload", the initial systemd announcement did a pretty
good job of explaining things...


Some of the details have evolved since then, but the higher level parts
should be accurate enough. The comments at the bottom are also worth
reading... though I have to say, Lennart must have a thick skin to put
up with some of the abuse he gets.

Somewhat balanced, perhaps. But I get a sense from there (and elsewhere)
that there are a lot of people take ideas like "do one thing well" and
"freedom of choice", and regard them as absolute holy law that must
never be questioned. And I tend to stop reading fairly quickly when I
see phrases like "people like him are poisonous" or other such abusive
