## Loading Kernel Modules ## Loading Kernel Modules
--- ---
Kernel modules can be automatically loaded with the `rancher.modules` cloud-config field.
```yaml
#cloud-config
rancher:
modules: [btrfs]
```
This functionality is also available via a kernel parameter. For example, the btrfs module could be automatically loaded with `rancher.modules=[btrfs]` as a kernel parameter.
### Loading Kernel Modules via a System Service
Privileged containers can load kernel modules. In RancherOS, the kernel modules are in the standard `/lib/modules/$(uname -r)` folder. If you want to be able to run `modprobe` from a container, you will need to bind mount the `/lib/modules` into your container. Privileged containers can load kernel modules.
