Package: lxc
Version: 1:3.1.0+really3.0.3-8
Severity: grave
Justification: renders package unusable

Dear Maintainer,

With the default setting, Devuan LXC package cannot start Fedora 30 and
Debian Stretch in LXC containers.
I suspect that LXC on Devuan always fails if /sbin/init in a container is systemd.

To reproduce the bug, do 

root@devuan:~# lxc-create -n stretch -t download -- -d debian -a amd64 -r stretch
Using image from local cache
Unpacking the rootfs

---
You just created a Debian stretch amd64 (20200424_05:24) container.

To enable SSH, run: apt install openssh-server
No default root or user password are set by LXC.
root@devuan:~# lxc-start -F -n stretch
Failed to mount cgroup at /sys/fs/cgroup/systemd: Operation not permitted
[!!!!!!] Failed to mount API filesystems, freezing.
Freezing execution.

root@devuan:~# lxc-create -n fedora30 -t download -- -d fedora -a amd64 -r 30
Setting up the GPG keyring
Downloading the image index
Downloading the rootfs
Downloading the metadata
The image cache is now ready
Unpacking the rootfs

---
You just created a Fedora 30 x86_64 (20200423_20:33) container.
root@devuan:~# lxc-start -F -n fedora30
Failed to mount cgroup at /sys/fs/cgroup/systemd: Operation not permitted
[!!!!!!] Failed to mount API filesystems.
Exiting PID 1...
root@devuan:~# exit 0
