Bug Report

I am trying to run the concourse worker in the following way:
/infrastructure/concourse/concourse worker --baggageclaim-driver=btrfs --work-dir /infrastructure/concourse/worker-state --tsa-host concourse-web.ger.corp.intel.com:2222 --http-proxy=proxy-chain.intel.com:911 --https-proxy=proxy-chain.intel.com:912 --no-proxy=10.109.80.95,127.0.0.1,localhost,.intel.com --tsa-public-key /infrastructure/concourse/keys/tsa_host_key.pub --tsa-worker-private-key /infrastructure/concourse/keys/worker_key

I am seeing the following error:
{"timestamp":"1525704710.857030153","source":"guardian","message":"guardian.create.create-failed-cleaningup.cleanedup","log_level":1,"data":{"cause":"runc run: exit status 1: container_linux.go:348: starting container process caused \" process_linux.go:402: container init caused \\\"rootfs_linux.go:46: preparing rootfs caused \\\\\\\"permission denied\\\\\\\"\\\"\"\n","handle":"1284f352-5f60-4d3c-69b6-3dfa26031b5c","session":"450.3"}}

The following can also be handy:

• Concourse version: 3.13.0
• Deployment type binary
• Infrastructure/IaaS: Linux concourse-w03 4.4.0-59-generic Stateful Hooks #80~14.04.1-Ubuntu SMP Fri Jan 6 18:02:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
