The Proxmox installer needs the full ISO to access packages and installer data. Previously the ISO was deleted after extracting kernel+initrd. Now we keep it as original.iso and serve it via HTTP. The iPXE script passes proxmox-iso-url=<url> so the installer fetches the ISO over the network instead of scanning block devices. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
