// iscsi_butane_setup.yaml contains the full butane config but here is an overview of the setup
// 1 - Boot a live ISO with two extra 10G disks with labels "target" and "var"
// - Format and mount `virtio-var` to /var
//
// 2 - target.container -> start an iscsi target, using quay.io/coreos-assembler/targetcli
// 3 - setup-targetcli.service calls /usr/local/bin/targetcli_script:
