# Linux Port

> [!WARNING]
> This page is very much a work in progress!

A _"linux system"_ comprises a few components:
1. A Kernel
2. A Root filesystem
3. Some utilities/commands

## Building
### Kernel
```
git clone --depth 1 --branch "v6.15" https://github.com/torvalds/linux
cd linux
make ARCH=m68k CROSS_COMPILE=m68k-linux-gnu- tinyconfig
make ARCH=m68k CROSS_COMPILE=m68k-linux-gnu- menuconfig
make ARCH=m68k CROSS_COMPILE=m68k-linux-gnu-
```

### Utilities
I am using BusyBox for a basic set of utilities
```
wget https://busybox.net/downloads/busybox-1.37.0.tar.bz2
tar xvf busybox-1.37.0.tar.bz2
cd busybox-1.37.0
make CROSS_COMPILE=m68k-linux-gnu- menuconfig
make CROSS_COMPILE=m68k-linux-gnu-
```
