This is an Alpine Linux based initramfs intended to exploit the bitpixie vulnerability.

It is based on a Filippo Valsorda's rootfs-free immutable NAS project.
See [frood, an Alpine initramfs NAS](https://words.filippo.io/dispatches/frood/).
To avoid confusion the script has been renamed to `bitpixie`.

You need to have Docker installed.

```
$ ./bitpixie build
$ ./bitpixie qemu     # optional sanity check
$ ./bitpixie deploy
```

In case you want to adapt it to your needs:

 - `packages` contains a list of alpine packages to install
 - `root` contains files and directories which will be copied to the initramfs
 - `setup.sh` is a shell script which is run during "installation" i.e. when `alpine-make-rootfs(1)` is executed
 - `bitpixie-build.sh` runs in an Alpine container and copies the necessary bitpixie related files into the initialramfs
