Subject: [PATCH] Add guidance when storage lacks rootdir support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Show actionable guidance when the selected storage does not support 'rootdir' content. Adds msg_custom lines with instructions to enable 'Disk image' (rootdir) for the storage (Datacenter → Storage → <name> → Edit → Content), plus links to the Proxmox storage docs and a GitHub discussions help page. Improves user troubleshooting before exiting with the existing error code.
