| # FS QA Test No. 261 |
| # |
| # This test exercises an issue in libxcmd where a problem with any |
| # mount point or project quota directory causes the program to exit |
| # complete. The effect of this is that one cannot operate on any |
| # directory, even if the problem directory is completely unrelated |
| # to the directory one wants to operate on. |
