Actually, IIRC, one directory was 42G, and the other was 15G or so. That,
along with reducing the reserved blocks on the f/s should have given me
3%-4%. I know that; what's driving me nuts is df, not df -h, is showing
"available" as a blank.

Oh, and for the other folks who wondered, we use rsync with hard links.
