  21 # Problem: Tar was not able to match directory name if the directory
  22 # member was split between two volumes
  23 # References: Jörg Schilling pretends to have reported this two
  24 # years ago (<42551FF2.nail98011FRAT@burner>).

  26 # Test idea:
  27 # 1. Create a listed-incremental archive of a directory containing
  28 # a cetrain number of zero-length files.
  29 # 2. Using the same snapshot file, create a *multivolume* listed-incremental
  30 # archive. Number of files created in the directory and volume size should
  31 # be selected so that the first volume ends in the midst of the directory
  32 # member. The files are zero-length so that their member records are
  33 # sufficiently small, in order for the entire archive to fit in two volumes.
  34 # 3. Test the created multi-volume archive.
