### Create filesystems

mkfs.fat -F 32 /dev/sda1
mkfs.ext4 /dev/sda3
mkswap /dev/sda2
swapon /dev/sda2

### Install base system

mkdir -p /mnt/gentoo/boot
mount /dev/sda3 /mnt/gentoo
cd /mnt/gentoo
wget https://gentoostudio.org/src/stage4-amd64-latest.tar.bz2
tar xvjpf stage4-amd64-latest.tar.bz2 --xattrs --numeric-owner
cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf

# Kernel is in /boot, so we need to move kernel files out of the way to mount sda1

mv /mnt/gentoo/boot/* /mnt/gentoo/kernfiles/
mount /dev/sda1 /mnt/gentoo/boot
mv /mnt/gentoo/kernfiles/* /mnt/gentoo/boot/

### Chroot into system and run chroot_install

mount -t proc /proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/dev
