Yeah. So the container job, it will be one systemd unit, and you'll see a bunch of processes in it. And you'll also see a couple of agents that we run, but mostly just the usual systemd PID1 inside the container and like their own instance of JournalD, LoginD and all that stuff.

Yeah.

Yeah.

Yeah, pretty much.

Yeah, pretty much.

So that part's a little newer than from the time I was in containers. But so you create a host profile, you work with like the host management team to do that. And then you can, I believe, specify it in your job spec. And then when you need to either restart your job or move the job around, they actually have to drain the host.

Most host profiles require a host restart, because things like huge pages, you need to restart the host to apply. And then the jobs gets started back up on the host with the host profile you're asking for.

Not specifically, but they do. So the host agent actually builds a lot of their components on top of system D as well. So they've been doing things like moving more configuration out of Chef into host agent where it's more predictable. So things like systemd networkd configs or the syscuddle configs that also go through systemd as well.

Oh, yeah. The tux hoodies. This is the one that Justin was talking about. That is so cool.

That's so cool. If anyone from scale is listening, they probably have a hoodie.

Yeah, I'd say at least the way the kernel team and our team operates is that we're mostly upstream first. Um, so everything that we write, we write it with like the idea that we're going to be upstreaming it. And that's how we managed to keep our team size small so that we don't have to maintain like a bunch of backports, things like that.

Yeah. So the kernel, we actually like, build and maintain internally. So we can kind of pull from the release whenever you want. And we can kind of do the same thing with CentOS too, because we all contribute to the CentOS hyperscale SIG. That's where any bleeding edge packages that we want to release immediately goes into the hyperscale SIG.
