http://bugzilla.opensuse.org/show_bug.cgi?id=1189793 http://bugzilla.opensuse.org/show_bug.cgi?id=1189793#c7 --- Comment #7 from Stefan Hundhammer <shundhammer@suse.com> --- I found it: https://github.com/yast/yast-installation/blob/master/startup/First-Stage/F1... # 10.1) reverse umount file systems... awk '/ \/mnt/{ print $2 }' /proc/mounts | sort -r | xargs --no-run-if-empty umount While this is very good to have as a last ditch defense, it's still scary that this is needed in this case: Something related to package handling (probably on the YaST side) keeps /mnt/var/cache/zypp busy. AFAICS it works well while RPMs are being installed: It only attaches /mnt/var/cache/zypp when it starts installing an RPM and then releases it again immediately. That's how it should be. But at the very end of the installation when files are copied over from the inst-sys to the target, some other code attaches to that directory and never releases it again. It is possible that some parts of libzypp are initialized again and never properly shut down. -- You are receiving this mail because: You are on the CC list for the bug.
