This coreutils bug report:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=61884
led to a change in behaviour such that `du -b`, which is equivalent to
`du --apparent --block-size=1`, reports directories as having zero size.
If we don't pass `--apparent` we restore the old output:
$ schroot -c sid -- du -s --block-size=1 /tmp/dired-du1wX4yG/empty-subdir
4096 /tmp/dired-du1wX4yG/empty-subdir
I've attached a minimal patch that fixes the bug:
