    unmount failure is not fatal
    
    There are several cases where the system can no longer access a mount
    point or a mount point configuration makes the algorithm bogus.
    
    For example, we mount something and then we chroot, the mount information
    will give an unaccessible path and the container won't be able to start
    because this mount point will be unaccessible. But if it's the case, then
    we can just warn and continue running the container.
    
    Another case is the path to a mount point is not accessible because there
    is another mount point on top of it hiding the mount point. So the umount
    will fail and the container won't start.
    
    Easy to reproduce:
    
    mkdir -p /tmp/dir1/dir2
    mount -t tmpfs tmpfs /tmp/dir1/dir2
    mount -t tmpfs tmpfs /tmp/dir1
    
    So can we just ignore the error when unmounting and continue to the list again
    and again until it shrinks.
    
    At the end, we just display the list of the unmounted points.
