| Presi300 | hello 👋 | 19:55:27 |
 Randy Eckenrode | Apple uses it for their userspace filesystem implementations. There were several false starts transitioning it from a private framework to a public one. I don’t know if anyone has tried implementing a filesystem (or FUSE) on top of it. It requires entitlements, so it’s probably not very useful for us. | 20:19:59 |
| Presi300 | how will nix-darwin's homebrew support handle pre-existing casks? | 20:20:42 |
| Randy Eckenrode | The example looks like an implementation of bind mounts. | 20:21:25 |
 WeetHet | I mean we can always ship a pre-built signed application alongside nix-darwin installation | 20:21:25 |
| WeetHet | I don't know what it can even be used for? | 20:21:43 |
| WeetHet | Mounting /opt/nix to /nix? | 20:21:49 |
| Randy Eckenrode | Filesystems. I wonder if it’s possible to use it to implement libfuse. Right now, the only implementations are proprietary. | 20:25:02 |
| Randy Eckenrode | * | 20:25:10 |
| WeetHet | Is macFUSE closed source? | 20:25:36 |
| Randy Eckenrode | Yes. That’s why we some stuff with stubs in Nixpkgs. | 20:26:05 |
| WeetHet | They claim to be using FSKit | 20:26:10 |
| Randy Eckenrode | * | 20:26:17 |
| Randy Eckenrode | It’s possible they changed the implementation in a recent release. | 20:26:42 |
| Randy Eckenrode | It would still be nice to have a copyleft implementation if only so we can distribute it. | 20:27:02 |
 samasaur | https://github.com/macfuse/macfuse/wiki/FUSE-Backends | 20:27:48 |
| samasaur | looks like they still default to a kernel extension and FSKit has a number of limitations | 20:28:14 |
| WeetHet |
Using mount points outside of /Volumes is not supported by FSKit.
This contradicts the Apple example, no?

| Randy Eckenrode | Were some of those relaxes in macOS 26? The example mounts outside of /Volumes. | 20:29:02 |

| WeetHet |
mount -t passthrough ~/Documents ~/passthrough-fs tells the extension to present the contents of your Documents directory as another file system, mounted at passthrough-fs
| 20:29:09 |
| samasaur | the macFUSE page could be wrong, that's just the latest information I see from them | 20:29:31 |
| WeetHet | How would nix even benefit from a fuse library for macOS? | 20:31:16 |
| WeetHet | Mounted wherever | 20:31:37 |
| WeetHet | Can't really use it for sandboxing | 20:31:58 |

 rebmit[reb] | maybe we could replace https://github.com/nix-darwin/nix-darwin/commit/1f9cca7781b18a073c45823a24e9bd74eb83d3fe with a bind mount? | 06:49:31 |
 toonn | Can't create bind mounts on macOS. | 08:35:19 |
