Instructions to set up syzkaller for a Linux Host and an amd64 NetBSD kernel.
## Setup the NetBSD sources
1. Get the NetBSD kernel source (preferably HEAD).
```sh
$ git clone https://github.com/NetBSD/src.git
```
2. Build the tools
```sh
$ cd src
$ ./build.sh -m amd64 -U -T ../tools tools
```
3. Build the Distribution (This might take a while)
```sh
$ cd src
$ ./build.sh -m amd64 -U -T ../tools -D ../dest distribution
```
