Re: Issue regarding running systemd under a container

[Atul Singh <atullh@xxxxxxxxx>]

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.
