[Bug 1149980] cleanup target system unmounting in umount_finish

https://bugzilla.suse.com/show_bug.cgi?id=1149980 https://bugzilla.suse.com/show_bug.cgi?id=1149980#c6 --- Comment #6 from Stefan Hundhammer <shundhammer@suse.com> --- It turns out that you can unmount btrfs subvolumes just fine; but at least one of them, /mnt/var, tends to be busy because libzypp uses /mnt/var/cache/zypp/packages/... for its package cache. If unmounting that one fails with a "busy" error, unmounting its parent Btrfs main volume at /mnt also fails with the same error. -- You are receiving this mail because: You are on the CC list for the bug.
