21 # This bug was fixed in coreutils-4.5.9.
22 # To exercise this bug is non-trivial:
23 # Set-up requires at least three hard-linked files. In copying them,
24 # while preserving links, the initial copy must succeed, the attempt
25 # to create the second file via `link' must fail, and the final `link'
26 # (to create the third) must succeed. Before the corresponding fix,
27 # the first and third destination files would not be linked.
29 # Note that this is nominally a test of `cp', yet it is in the tests/mv
30 # directory, because it requires use of the --preserve=link option that
31 # mv enables by default.
