http://bugzilla.suse.com/show_bug.cgi?id=1008898 Bug ID: 1008898 Summary: KIWI can't unmount sysfs (is in use by systemd-logind) Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: ms@suse.com Reporter: svollath@suse.com QA Contact: qa-bugs@suse.de CC: thardeck@suse.com Found By: --- Blocker: --- Created attachment 700932 --> http://bugzilla.suse.com/attachment.cgi?id=700932&action=edit KIWI logs + config When building an appliance with kiwi (in this case using "machinery build"), kiwi finishes SUCCESSFUL, but machinery can't cleanup its temporary files. This is because kiwi leaves a sysfs mount open which requires a reboot to get rid of. ((Reproduced with Leap 42.1, 42.2, kiwi-7.03.97, kiwi-7.04.8, kiwi-7.04.13)) Buildlog snippets: ...

http://bugzilla.suse.com/show_bug.cgi?id=1008898 http://bugzilla.suse.com/show_bug.cgi?id=1008898#c1 --- Comment #1 from David Cassany <dcassany@suse.com> --- After digging a while I found that this issue is produced by the installation of apparmor-profiles package. The installation of this package causes a restart of the apparmor service which somehow leaves something opened (I couldn't actually figure out what) related to the chrooted /sys. I am passing this issue to apparmor maintainers, I hope they can debug what is actually happening here when installing apparmor packages in a chrooted env. -- You are receiving this mail because: You are on the CC list for the bug.
