Hi there!

Bug Report

Hi, we worked with https://github.com/cloudfoundry/bosh-linux-stemcell-builder to builder our stemcells. And everything worked well in concourse 2.6.9. But in v3.4.1, the build-softlayer-xen-ubuntu-trusty task failed to run bundle exec rake stemcell:build such as:

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
  behaves like every OS image
    installed by base_<os>
      #<ShelloutTypes::Command:0x0055e78c4d5e80>
        has exit status of 0 (FAILED - 1)
      #<ShelloutTypes::Command:0x0055e78c4d20f0>
        has exit status of 0 (FAILED - 2)

That means to read the /etc/sudoers file in the base image.

We knew the stemcell team did not use v3.0. But we really hope to be able to use the latest version. I thought these is a major change between v2 and v3.

The following can also be handy:

• Concourse version: 3.4.1
• Deployment type (BOSH/Docker/binary): BOSH
• Infrastructure/IaaS: Softlayer
• Browser (if applicable):
• Did this used to work? In the older version, it was work.
