That's what I thought; I've never sync'ed stuff before unmounting it before,
and chats with other BSD bods in my area say that just unmounting will do -
and I think I'll stick to that.

Unmount does not return until the buffers have been synced anyway, so this
does not buy you anything.

The ancient form is more like:

sync;sync;sync;<halt button on your PDP/11 frontpanel>
