I reported a strange bug in which a user cannot unmount an USB device if it is not in /etc/fstab. Well, it became very strange when I saw that if I install openSUSE Tumbleweed from the GNOME LiveCD then I **do not** have the problem, whereas the problem occurs if I install from the standard DVD.
After a careful digging, it turns out that the problem is caused because /var/run is not a symlink to /run when I install Tumbleweed from the standard DVD. When the installation is done from the GNOME LiveCD, then /var/run is indeed a symlink to /run and the problem does not occur.
Hence, my question is: must /var/run always be a symlink to /run ? If so, I think we need to open a bug against openSUSE installation software.
Notice that I could fix the problem when I enter in the system in maintenance mode, unmount /var/run, deleted it, and then symlink /run to /var/run.
