remote-exec stops executing after running sudo systemctl start

[paulczar]

This applys to the current release v0.6.13... v0.6.8 works as expected.

This means only the first service that I ask for actually starts in the current version, whereas the earlier version it all starts up as expected.

Code Snippet

The following block in remote-exec:

    provisioner "remote-exec" {
        inline = [
            "echo '==> Services'",
            "echo '----> starting registrator'",
            "sudo systemctl start registrator.service",
            "echo '----> starting swarm-agent'",
            "sudo systemctl start swarm-agent.service",
            "echo '----> starting swarm-manager'",
            "sudo systemctl start swarm-manager.service",
        ]
    }

Run output - v0.6.13

Hi @paulczar - thanks for the report and sorry for the trouble here! Looks like the attempt to clean up remote exec scripts in v0.6.13 had an unexpected race condition. Fixed on master and will be fixed in 0.6.14 to be released later today.
