 - Partition disks and create filesystems
 - Mount partitions - don't worry about bind mounting, arch-chroot will take care of that.
 - Add repos to the new root partition with zypper. Example for TW:
zypper --root /mnt/os ar -p 95 https://download.opensuse.org/tumbleweed/repo/oss/ oss
zypper --root /mnt/os ar -p 95 https://download.opensuse.org/tumbleweed/repo/non-oss/ non-oss
zypper --root /mnt/os ar -p 90 https://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Tumbleweed packman

 - Edit the new root's /etc/zypp/zypp.conf to your liking. onlyRequire, allow-vendor-change, etc
 - Install packages. For a barebones basic system:
zypper --root /mnt/os in kernel-default grub2 dracut zypper bash man nano shadow util-linux ca-certificates dhcpcd

 - Chroot. Use arch-chroot
 - Set timezone
 - Configure lang/locale and keymap
 - Define /etc/hostname
 - Enable systemd services
 - Install bootloader
 - Configure and generate initrd
 - Create user and set passwords
