cgroup v1 was supported by systemd through version 257, which is what shipped in trixie. As such, we should keep cgroup v1 entries even though they may not see much use on "current" systems. As you note below, a warning may be generated, but I think that's OK as there's no impact on the running containers. > I'm no expert, but I suspect that's the reason for these warnings: > > lxc max-wp1 20241104110429.560 WARN cgfsng - > ../src/lxc/cgroups/cgfsng.c:cgfsng_setup_limits_legacy:3155 - Invalid > argument - Ignoring legacy cgroup limits on pure cgroup2 system > > That may be just a warning, but presumably this is ineffective, and > there should be equivalent cgroup2 lines somewhere? The packaging of lxc-templates for trixie includes corresponding cgroup v2 rules in /usr/share/lxc/config/debian.common.conf. > I'm still running bookworm, but I checked the trixie package, and > that file has the same entries in it. lxc-templates is considered deprecated in favor of distrobuilder by upstream. I expect that lxc-templates will be removed during the forky+1 development cycle. However, if you would like to make improvements (such as removing cgroup v1 rules for the forky release), please feel free to do so. I would suggest starting be looking at some of the Debian-specific patches, then working to get any relevant changes merged into the upstream project. That will benefit all distros, and will be easy to incorporate into packaging updates for Debian. Mathias
