Hello,

I've been trying to get some of my containers to work under RHEL 7.4 with the --init flag introduced in Docker 1.13. However, so far I could't get them running as soon as the flag is added.

Docker info:

When I try to run a container with the --init flag, I receive the following error:

Error response from daemon: exec: "docker-init": executable file not found in $PATH

Which makes sense as "docker-init" simply is not present as it seems to be "docker-latest-init" in the docker-latest package. Even after adding /usr/libexec/docker (location of docker-latest-init) to $PATH the error stayed the same. I simply tried to change the name of "docker-init-latest" to "docker-init" which resulted in the container starting and immediately restarting. The logs then showed:

"exec -- failed: No such file or directory"

I completely removed docker and then tried out the latest Docker-CE which worked perfectly on the first try.
Does anyone have any idea what I'm doing wrong?

Thanks
