@3246 yes, kind of like a torrent file where you can select priority per file/dir and which ones to skip.
not sure a pause is needed, but more like a pre-start selection.
I'm sure @staff can enumerate mail and other core services as required items but with flexible priority/order.
Not only that, but while we're pondering that manual selection process with manual clicks, the essential bits can already be restored and ready for the next prioritized components.
