+# ==========================================================
+# Shared helpers for VM ISO selection. Proxmox identifies ISO media by
+# volume ID (for example: local:iso/debian.iso or nas:iso/win11.iso);
+# using the volid lets VMs boot ISOs stored on local, NFS, CIFS or any
+# other storage that advertises content=iso.
