Maybe that's the reason though?
| 20:30:40 |
| matthewcroughan | Yeah okay, maybe that's all it is.. | 20:31:56 |
 lassulus | seems like it can't find the key | 20:34:16 |
| lassulus | so probably unrelated | 20:34:20 |
| matthewcroughan | but how does this succeed in the installer test ? | 20:34:30 |
| matthewcroughan | but not in disk image building | 20:34:33 |
| matthewcroughan | is the exit code ignored in the installer test? | 20:34:40 |
| lassulus | it probably creates /tmp/secret.key? | 20:34:48 |
| matthewcroughan | ah yeah it does | 20:35:00 |
| matthewcroughan | lib/tests.nix does this for tests | 20:35:13 |
| matthewcroughan | Okay, so imageSize being set wrong, or errors in the disko config can both lead to kernel panics | 20:37:30 |
| matthewcroughan | and ofc not enough space | 20:37:51 |
| lassulus | hm errors in the config should lead to eval errors | 20:37:58 |
| matthewcroughan | so it's very easy to conflate that with other things, but I think I have an actual reproducer now | 20:38:01 |
| matthewcroughan | you do need an image of a certain size before memory becomes an issue | 20:38:17 |
| lassulus | except if they are like not catched errors :D | 20:38:17 |
| matthewcroughan | By wrong I meant too small | 20:39:08 |
| matthewcroughan | which the eval can't catch | 20:39:10 |

|  amadaluzia -> 4d2.org changed their display name from amadaluzia[uorg] to amadaluzia -> 4d2.org. | 21:23:09 |
| matthewcroughan | If it is possible to reproduce it on other FS, I couldn't figure that out after a few hours of trying | 21:26:59 |
| matthewcroughan | CI seems to fail for some reason that I don't get on my end | 21:28:57 |
