 The Keepalived deployment additionally requires a healthy, quorate Proxmox
 cluster and passwordless root SSH between cluster nodes.
 
+The shared ISO storage wizard creates a privileged Debian LXC with a dedicated
+secondary volume, restricts its NFS export to a supplied client CIDR, and adds
+the export to Proxmox's cluster-wide storage configuration. The container host
+and network path to the container must remain available for nodes to use the
+ISO repository.

 The legacy Dell OMSA installer is limited to supported PowerEdge x30/x40
 systems running Proxmox VE 9 on Debian 13 (Trixie), amd64.
