Andrew Geissler | 78b7279 | 2022-06-14 06:47:25 -0500 | [diff] [blame] | 1 | There are two issues here. Firstly, the modules are accessed in on disk order. This |
| 2 | means behaviour seen on one system might not reproduce on another and is a real headache. |
| 3 | |
| 4 | Secondly, empty directories left behind by previous modules might be looked at. This |
| 5 | has caused a long string of different issues for us. |
| 6 | |
| 7 | As a result, patch this to a behaviour which works for us. |

| 9 | Upstream-Status: Pending [need to talk to upstream to see if they'll take one or both fixes] |
