arch-ansible

• sshpass needed to authenticate to the Arch ISO with no password prompt.
• host_key_checking = False and UserKnownHostsFile=/dev/null - Arch ISO regenerates its SSH host key on every boot. If you have installed on the machine before, your known_hosts has a stale key and SSH would refuse to connect. This bypasses that.
• Connect as root on the ISO so no sudo to worry about.

ansible.cfg

• no ansible_password, instead we pass --ask-pass at runtime and type it once. Typing default password once is fine as it allows the file to be free of secrets.
