3. become root
4. apt update
5. apt install rpm zypper curl btrfs-progs zstd parted
6. wipe existing block devices `for d in a b; do wipefs -a /dev/xvd${d}; done`
7. create partitions
   1. parted -s /dev/xvda mklabel gpt mkpart root btrfs 0% 100%
   2. parted -s /dev/xvda set 1 boot on
   3. parted -s /dev/xvdb mklabel gpt mkpart swap linux-swap 0% 100%
   4. mkfs.btrfs /dev/xvda1
   5. mkswap -L SWAP /dev/xvdb1
8. mkdir -vp /target && mount -v /dev/xvda1 /target
9. cp -v /etc/resolv.conf /target/etc/
10. set up repo files
    1. mkdir -p /target/etc/zypp/repos.d/
    2. cat <<-EOF > /target/etc/zypp/repos.d/repo-oss.repo

1. run `zypper --releasever=15.3 -R /target install zypper`
   1. trust the key
   2. say yes to everything else
2. chroot

mount -v --bind /dev /target/dev

mount -v --bind /dev /target/dev

1. passwd root
2. openSUSE doesn't currently have selinux enabled by default, but if that changes in future you'll need to ask for a relabel *and* disable it for the first boot
3. exit chroot and dismount

exit
umount /target/sys
umount /target/proc
umount /target/dev
umount /target

1. halt
