## Use with LinuxKit images
You can build a LinuxKit image suitable for `crosvm` with the
`kernel+squashfs` build format. For example, using this LinuxKit
YAML file (`minimal.yml`):
```
kernel:
image: linuxkit/kernel:4.9.135
cmdline: "console=tty0 console=ttyS0 console=ttyAMA0"
init:
- linuxkit/init:6eb0158059b056a1567236280880cb87f03ff008
- linuxkit/runc:6cf26a0403376de3b5396cb676b88eea4f37aff8
- linuxkit/containerd:d955db7cd28dbd7be8a17d7063cc6b7f1bf91f0a
services:
- name: getty
image: linuxkit/getty:v0.6
env:
- INSECURE=true
trust:
org:

```

the `./examples` directory, run:
```sh
linuxkit build -output kernel+squashfs minimal.yml
linuxkit build -format kernel+squashfs minimal.yml
