The way it was explained to me was that the old way fell down in some |
| 8 |
situations with multiple interfaces. Interfaces were named in the |
| 9 |
order they were disovered by the kernel during startup. For some |
| 10 |
sorts of NICs (e.g. PCI) the discovery order is repeatible, so no |
| 11 |
problems. |

However, for some sorts of interfaces (e.g. USB attached devices), the |
| 14 |
discovery order isn't always repeatable. The new scheme was |
| 15 |
implemented to make sure than every time you reboot you get interface |
| 16 |
names that corresponded to the same physical RJ45 jacks they did the |
| 17 |
last time. |
