The message about cgroup v1 on line 29 should also be removed.
Is there maybe also documentation referring to cgroup v1/2?

Done, also good call on the documentation, fixed that as well
All relevant environments (Debian, Ubuntu, RedHat, ArchLinux, WSL2, Fedora) support and default to cgroup v2 since years, and it helps with simplification of runguard, which is a precursor of merging runpipe and runguard.
I actually have to (overdue) upgrade to latest Debian release from 2 months ago to have a supported (default) kernel, so "years" is not quite true. |

I took this from https://wiki.debian.org/LXC/CGroupV2 where it reads "Starting with Linux kernel 4.5 (Debian Bullseye or later), cgroups v2 is now the default." |
Yeah, but we require kernel >= 5.19 to "record peak RAM usage with cgroup V2". OTOH, I noticed I was running an old kernel, so on Debian Bookworm (oldstable), 6.1.0 was actually the default kernel, so actually since 2 years our setup was fully supported on Debian :-) |
