# Introduction
The repository is an exploration of the question: what if we wanted to use
the Linux kernel as a poor man's microkernel? Microkernels are cool and all,
but figuring out how to deal with all the device drivers is a bit soul
crushing. So here, we're going to skip over those details, and see what it'd
look like if we just built everything else: the network stack, the file
systems, the graphical infrastructure, virtualization, etc. And let's use
Rust to do it, because I'm a fanboy. And let's not keep ourselves to
POSIX and standard Linux file system organization, because why bother?
# To Hit Go
Well, you'll need [Docker](https://www.docker.com/products/docker-desktop).
You'll need to use a fancy Rust Docker container or two. Run this:
```
% ./scripts/build-docker-envs.sh
```
To build your handy-dandy Docker containers.
To build the linux kernel, which you'll need, you should run:
```
% ./scripts/build-kernel.sh
```
You'll then want to run the Rust build:
```
% cargo build --release --target x86_65-unknown-linux-musl
```
And then build this all up into a nice ramdisk:
```
% ./scripts/build-ramfs.sh
```
And run the demo:
```
% ./scripts/run.sh
```
Wheee!! Fun!!
