This patch checks if a directory is mounted under the chroot and skips rmrf() if there is one.
** Patch added: "cowdancer_0.71ubuntu1.debdiff" https://bugs.launchpad.net/ubuntu/+source/cowdancer/+bug/1156540/+attachment/3582728/+files/cowdancer_0.71ubuntu1.debdiff ** Description changed: If cowbuilder failed to unmount a bind-mounted directory (device busy for example) it unconditionally deletes its content during the clean-up phase. Excerpt from a log with this bug (complete log attached) ===== I: umounting /var/lib/jenkins/cu2d umount: /var/cache/pbuilder/build/cow.15281/var/lib/jenkins/cu2d: device is busy. - (In some cases useful info about processes that use - the device is found by lsof(8) or fuser(1)) + (In some cases useful info about processes that use + the device is found by lsof(8) or fuser(1)) [...] - -> Cleaning COW directory - forking: rm -rf /var/cache/pbuilder/build//cow.1195 + -> Cleaning COW directory + forking: rm -rf /var/cache/pbuilder/build//cow.1195 rm: cannot remove `/var/cache/pbuilder/build//cow.1195/var/cache/pbuilder/ccache': Device or resource busy rm: cannot remove `/var/cache/pbuilder/build//cow.1195/var/lib/jenkins/cu2d/work/experimental/100scopes': Device or resource busy rm: cannot remove `/var/cache/pbuilder/build//cow.1195/var/lib/jenkins/cu2d/launchpad.cache': Directory not empty ===== The 'rm' command must skip directories on other filesystems + + This bug occurs when pbuilder fails to mount all the bindmounted + directories, then fails to unmount previously successfully mounted + directories.
