`aios`とは自作osのことで、archlinuxをベースにしていました。

```sh
#!/bin/zsh
git clone https://gitlab.archlinux.org/archlinux/archiso
cp -rf ./cfg/profiledef.sh ./archiso/configs/releng/profiledef.sh
cp -rf ./cfg/profiledef.sh ./archiso/configs/baseline/profiledef.sh
cp -rf ./scpt/mkarchiso ./archiso/archiso/mkarchiso
./archiso/archiso/mkarchiso -v -o ./ ./archiso/configs/releng/
tar xf aios-bootstrap*.tar.gz
mkdir -p root.x86_64/var/lib/machines/arch
pacstrap -c root.x86_64/var/lib/machines/arch base
echo -e 'Server = http://mirrors.cat.net/archlinux/$repo/os/$arch
Server = https://geo.mirror.pkgbuild.com/$repo/os/$arch' >> ./root.x86_64/etc/pacman.d/mirrorlist
sed -i s/CheckSpace/#CheckeSpace/ root.x86_64/etc/pacman.conf
arch-chroot root.x86_64 /bin/sh -c 'pacman-key --init'
arch-chroot root.x86_64 /bin/sh -c 'pacman-key --populate archlinux'
arch-chroot root.x86_64 /bin/sh -c 'pacman -Syu --noconfirm base base-devel linux'
tar -zcvf aios-bootstrap.tar.gz root.x86_64/
```

## rust + unix

一からosを作りたいと思っていたので、rustでunixのosを作り始めました。

名前は`Aios`にして、今回は`syui`のprojectとして作り始めました。

後に`ai/os`と統合するかもしれません。

2. [https://git.syui.ai/syui/aios](https://git.syui.ai/syui/aios)

```sh
#!/bin/zsh
d=${0:a:h:h}
cd $d/kernel
cargo bootimage --release
BOOT_IMAGE="../target/x86_64-unknown-none/release/bootimage-aios-kernel.bin"
qemu-system-x86_64 -drive format=raw,file="$BOOT_IMAGE"
```
