Thank you for looking into it. Sorry for the long delay, but my answers got blocked by xmission several times and I think I just gave up on containers at some point. This is still not solved though. To answer Eric's question:

It is now called after the network namespace rather than being called sysfs, that's why I missed it last time. It looks like: testns on /sys type sysfs (rw,relatime) So that's probably not a problem. So it seems the code of `ip netns exec` still hasn't been updated not to lose cgroups and all other system mounts... I just checked with 5.2.14-arch2-1-ARCH Thanks in advance, Naja Melan
