Subject: bug#20578: du counts a multiple times bind-mounted directory just for the first listed directory in a directory lists
Date: Thu, 14 May 2015 20:37:23 +0200

I created few chroot image, each conteaining a Gentoo Linux minimal image.

I do bind-mount a directory from the host (~35 GB of downloaded package files) onto a directory of each of the chroots to save space and bandwith.
A "du -ms" however counts that value just for the first listed directories:

tor-relay /mnt/qa/tinderbox # du -ms amd64-hardened-stable_* amd64-hardened-unstable_* 2>/dev/null
42318   amd64-hardened-stable_20150513-221439
11948   amd64-hardened-unstable_20150513-215830

tor-relay /mnt/qa/tinderbox # du -ms amd64-hardened-unstable_* amd64-hardened-stable_* 2>/dev/null
48790   amd64-hardened-unstable_20150513-215830
5434    amd64-hardened-stable_20150513-221439
