Dear Michael and the Debian maintainers of LXC,

I suggest to close this issue #944389. The reason is that

Addition of

lxc.cgroup.devices.allow =
lxc.cgroup.devices.deny =
lxc.init.cmd = /lib/systemd/systemd systemd.unified_cgroup_hierarchy=1

to a container config allows normal start-up of an LXC container when
/sbin/init is a recent version of systemd, and only

lxc.cgroup.devices.deny =
lxc.cgroup.devices.allow =

are sufficient when /sbin/init is not systemd, for the latest Debian LXC package
3.1.0+really3.0.4-2 made on August 2019 running on a Debian Bullseye booted
with systemd.unified_cgroup_hierarchy=1

This #944389 seems a documentation issue that should be fixed at
and does not seems an issue in the Debian package or the upstream
(except possible update to README.Debian).

Best regards, Ryutaroh Matsumoto
