I must be doing something wrong here but can't figure out what.
$ imagebuilder -t foo -f Dockerfile.min .

$ docker run -it --rm foo

First of all, where did "sleep 86400" come from? fedora:27 has no Cmd or Entrypoint set. foo does.
$ docker run -it --rm fedora:27

I must be doing something wrong here but can't figure out what.
With imagebuilder from latest head, and docker-1.13.1-51.git4032bd5.fc27.x86_64
First of all, where did "sleep 86400" come from? fedora:27 has no Cmd or Entrypoint set. foo does.
Second, why does it fail to run that?
