IIRC, tar pads out its files to end on a 10k boundary, and has internal
padding such that even a 1-byte files takes about 1k to store. Hence, I
wouldn't quite go as far to say "no waste of space due to the fs" -- as
long as you're willing to consider the tar format a filesystem for those

(yes, I'm nitpicking -- sorry).
