Hello, starting this container on a stock Debian 11 Bullseye errors out.
It seems to me it should be supported, from this comment and thread:
<https://github.com/lxc/lxc/issues/2033#issuecomment-354982434>.
However, changing the config to match that POC gives the same error.
What's missing? Should I ask upstream?
$ cat > test_config <<EOF
