nvidia-docker does not work with complex commands

[elezar]

When running the following command:

docker run --rm -ti nvidia/cuda:7.5-cudnn4-devel /bin/bash -ci 'groupadd -f -g 1000 dummy && useradd -u 1000 -g dummy dummy && mkdir --parent /home/dummy && chown -R dummy:dummy /home/dummy && sudo -u dummy HOME=/home/dummy bash'

The container starts as expected, and the prompt is shown as:

`````` dummy@e7ffa1ea404f:/$```

When I use the nvidia-docker wrapper, however:

GPU=0 nvidia-docker run --rm -ti nvidia/cuda:7.5-cudnn4-devel /bin/bash -ci 'groupadd -f -g 1000 dummy && useradd -u 1000 -g dummy dummy && mkdir --parent /home/dummy && chown -R dummy:dummy /home/dummy && sudo -u dummy HOME=/home/dummy bash'

```
the following output is shown:
```

[ NVIDIA ] =INFO= Driver version: 352.63
[ NVIDIA ] =INFO= CUDA image version: 7.5

Usage: groupadd [options] GROUP

Options:
  -f, --force                   exit successfully if the group already exists,
                                and cancel -g if the GID is already used
  -g, --gid GID                 use GID for the new group
  -h, --help                    display this help message and exit
  -K, --key KEY=VALUE           override /etc/login.defs defaults
  -o, --non-unique              allow to create groups with duplicate
                                (non-unique) GID
  -p, --password PASSWORD       use this encrypted password for the new group
  -r, --system                  create a system account
  -R, --root CHROOT_DIR         directory to chroot into

and the container is not started.

Changing the last line of the nvidia-docker wrapper to:
$DOCKER $DOCKER_ARGS $NV_DOCKER_ARGS "$@"
seems to address this.

Thank you for reporting this issue, this should be fixed in the upcoming overhaul of nvidia-docker (which you can already peek on the v1 branch).
