I see, so we made a patch for repo-add :
I also made one for makepkg : http://bugs.archlinux.org/task/11225?getfile=2426

But Dan rejected it with this reason :
"Note that I did not touch makepkg because our size there is not
critical- a size to the nearest K is just fine, and switching to a
find/stat way of doing it would cause all hard links to get

It is a size to the nearest K for each file, and we accumulate the errors ?
I did not realize the difference was so big until today, when playing
with docsize stuff.

e.g. for libsigc++-2.0 :
du -s = 12040 K
du -s --apparent-size = 10723 K

So that's 1300K. and 12% error if I am not mistaken.
