Hello, I copy-pasted configuration and commands from /usr/share/doc/lxc/README.Debian.gz under "Unprivileged containers". Are you talking about another file? https://salsa.debian.org/lxc-team/lxc/-/blob/7d692c266c63fced9417042ae904cc2a280b96d8/debian/README.Debian
lxc.rootfs defaults to the system root / per lxc.container.conf(5). Creation is unnecessary, it is just a convenience to avoid -f and does not affect the container runtime. My (still privileged) lxc setup works perfectly with -f without ever creating any containers. I pasted full logs above. Please try to be respectful and helpful, do not reproduce on a configured machine, and leave bug triaging to the lxc experts. Thanks,
