This adds a small C binary for fighting zombies. It is mounted under
`/dev/init` and is prepended to the args specified by the user. You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.
You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.
You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.
```c
int main(int argc, char ** argv) {
pid_t pid = fork();
if (pid == 0) {
pid = fork();
if (pid == 0) {
exit(0);
}
sleep(3);
exit(0);
}
printf("got pid %d and exited\n", pid);
sleep(20);
}
```

This directory holds scripts called by make.sh in the parent directory.
Each script is named after the bundle it creates. They should not be called directly - instead, pass it as argument to make.sh, for example:
./hack/make.sh test
./hack/make.sh binary ubuntu
# Or to run all bundles:
./hack/make.sh
To add a bundle:
- Create a shell-compatible file here
- Add it to $DEFAULT_BUNDLES in make.sh
