ACME / Let's Encrypt integration for z/VM
Way too early to be usable
The plan is to use IUCV to bind port 80 on the z/VM TCPIP service machine. This together with a minimal zLinux kernel and a single userspace binary should be enough to make z/VM be able to respond to HTTP-01 requests.
The userspace binary will be a Go binary using the ACME libraries it provides.
