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