This enables warden stemcells to function on hosts that are using cgroups v2, which is increasingly common. This should not have any effects on other infrastructures as the stemcell kernel will continue to be booted with cgroups v1.

I think this looks good to me. The main change is to use a cgroup v2 path instead of a v1 path when necessary? |

There was a problem hiding this comment.
This change seems reasonable for contexts where a Jammy stemcell image is be running in a containerized context.

Something similar would be needed here: https://github.com/cloudfoundry/bosh-linux-stemcell-builder/blob/ubuntu-noble/stemcell_builder/stages/bosh_monit/assets/monit-nftables.nft#L9 So the question on my mind is why is this needed on a noble host, and why only when using the warden cpi. Because noble host with docker cpi is fine, with both noble and jammy stemcells. In other words shouldn't this be fixed on the garden noble compatibility side? |
