I'm currently managing development VMs (mostly Fedora Cloud) using Ansible on a Proxmox hypervisor and i'm mostly happy with how it works. I'm interested in experimenting with immutable OS's , the most immediate difference I see is that I'd have to start using Butane instead of CloudInit. Can anyone with experience comment on the pros and cons ? Right now, I really do everything in Ansible, including creating the VMs from a proxmox clone template.
