Comment 6 for bug 1933128

Unfortunately we do not have Juju openstack anymore to reproduce or get these logs - snap store failed to download correctly yet again, that broke etcd and vault, which broke the entire stack and it was the final straw. We've since elected to use Kolla for OpenStack (also gives us access to a bunch of pieces not available in the Juju stack, such as Zun) while leveraging Juju for Ceph only. The dependency of private cloud components on a public resource (snap store) sort of defeats the purpose of building private in the first place (independence from vendor/provider shenanigans).

Anecdotally however i have found that cgroup issues on systemd hosts are plentiful and irritating. We use Arch internally so get to "play with" all of the newest changes to systemd and the underlying OS, and its been a roller-coaster of kernel commandline options for hierarchy, container runtime configs, and scripted cgroup mappings to keep older containers running on newer systems (the insanity in LXC/LXD hasn't helped, nor has the general variety of OCI environments). Since you guys are a versioned distro (vs rolling), it shouldn't be quite as bad in-version, but i'm guessing some of these breaking changes get backported once in a while and then fixed once folks realize they can't run previously created containers correctly.
