[systemd-devel] Issue regarding running systemd under a container

[Atul Singh]

Hello systemd-devel,

I am working to dockerize the buildroot based rootfs.
While dockerization if I run the container with privilege mode am able to
run the container and it works fine.

But, when I try to run/restart other containers I get the below error
message during docker run.

Please advise how to resolve this issue.
