| 8 | configuration combinations are rarely, if ever, tested. DevStack is not |
| 9 | a general OpenStack installer and was never meant to be everything to |

| Sean M. Collins | 09e550c | 2014-10-21 11:40:08 -0400 | [diff] [blame] | 28 | - Other OS platforms may continue to be included but the maintenance of |
| 29 | those platforms shall not be assumed simply due to their presence. |
| 30 | Having a listed point-of-contact for each additional OS will greatly |
| 31 | increase its chance of being well-maintained. |
| 32 | - Patches for Ubuntu and/or Fedora will not be held up due to |
| 33 | side-effects on other OS platforms. |
