fuse fix

Looking deeper, the above is not entirely correct. Fuse versions 2.7.* and 2.8.* are all affected. The fix needs "--no-canonicalize" and "--fake" options in umount(8), which is present in util-linux-ng >= 2.18.

The following commits need backporting to earlier versions of util-linux-ng:

  45fc569a75 mount: add --no-canonicalize option
  be9adec40f mount: disable --no-canonicalize for non-root users
  387ade2a24 umount: add --no-canonicalize
  97a3cef4f1 umount: add --fake option to umount(8)
  1cf4c20b19 mount: don't canonicalize "spec" with --no-canonicalize option
