@xokdvium I think the constructor for I am not sure how to fix this with the old settings system. Of course, my new store settings system in #11139 is designed to fix just these sorts of issues, but the point of splitting out this PR was to not do that refactor just yet. Any ideas? (I am running UBSAN right now to check this hypothesis.) |

We can gut out some gratuitous inhertence as follows: - `MixStoreDirMethods` -> `StoreDir` - `StoreDirConfig` deleted because no longer needed. It is just folded into `StoreConfig`. - `StoreDirConfigBase` -> `StoreConfigBase` same trick still needed, but now is for `StoreConfig` not `StoreDirConfig` Here's how we got here: 1. I once factored out `StoreDirConfig` in NixOS#6236. 2. I factored out `MixStoreDirMethods` in NixOS#13154. But, I didn't realize at point (2) that we didn't need `StoreDirConfig` anymore, all uses of `StoreDirConfig` could instead be uses of `MixStoreDirMethods`. Now I am doing that, and renaming `MixStoreDirMethods` to just `StoreDir` because `MixStoreDirMethods` is an unnecessarily weird name.
