```
The above issue can be resolved by setting `storage_driver: vfs` in the `.drone.yml` file. This may work, but will have very poor performance as discussed [here](https://github.com/rancher/docker-from-scratch/issues/20).
This error occurs when using Debian wheezy or jessie and cgroups memory features are not configured at the kernel level:
```

```
The above issue can be resolved by editing your `grub.cfg` and adding `cgroup_enable=memory swapaccount=1` to you kernel image. This change should look like that afterwards:
```
