Hi,
running binary verison 1.6 with following:
./concourse_linux_amd64 web --basic-auth-username myuser --basic-auth-password mypass --session-signing-key keys/session_signing_key --tsa-host-key keys/host_key --tsa-authorized-keys keys/authorized_worker_keys --external-url http://ci.mysite.com --postgres-data-source postgres://postgres:postgres@localhost:5432/atc?sslmode=disable

I cant run simplest commands.
I get this error both on Ubuntu 16:04 docker 1.12.1 and debian 8.5 on Docker 1.11.1:
runc create: exit status 1: rootfs_linux.go:42: preparing rootfs caused "permission denied"

folowing runs perfectly:
docker run busybox /bin/echo hello world

I found folowing bug in docker issues:
moby/moby#25847

but cant you just make a work around or inform me of working setup?

I tried CeontOS 7.2 and docker 1.10, but it gives capability error, searching the web it implies I need kernel 3.19 or higher, latest CentOS comes with 3.13

totally locked up.
how do you run concourse? in which distro and setup that it works?
