Hi, I was recently searching for running systemd in a docker container, and I have found systemd-containers on fedora wiki. I followed the instructions but got the following output: 

[root@localhost Dockertest]# docker run -ti --tmpfs /run --tmpfs /tmp -v /sys/fs/cgroup:/sys/fs/cgroup:ro fedora:systemd

Welcome to Fedora 28 (Twenty Eight)!

My system is a fedora 28 VM, my docker version is docker-1.13.1-51.git4032bd5.fc28.x86_64, and the dockerfile used to build is,

FROM registry.fedoraproject.org/fedora:28
ENV container=oci
RUN dnf -y install httpd; dnf clean all; systemctl enable httpd
STOPSIGNAL SIGRTMIN+3
EXPOSE 80
CMD [ "/sbin/init" ]

I also saw a similar error on https://bugzilla.redhat.com/show_bug.cgi?id=1402264, but I did not install oci-systemd-hook at all on my host. Any suggestions for how to approach/fix the problem? Thanks =).
