 Khalil Santana | I was trying to setup profiling in nix using this[1] to figure out why colmena is slower, but didn't quite succeed (I think I got a -ENOSPC or something due to /tmp/ as tmpfs or something). Do you think something like this would be useful to debug this performance behaviour?

Yeah, I think something like this is useful in general, not just for colmena but for nixpkgs slowness as well | 16:04:20 |
| Zhaofeng Li | Also the issue I linked above has a list of commands that correspond to what Colmena actually evaluates underneath, so you can manually invoke the same evaluation in the profiler | 16:04:25 |
| Khalil Santana | Heh, it seems that plotting the flamegraph it is not quite possible in my system with 32GB of RAM.:

 marshmallow | Am i crazy or did the makeHive change and the flake output being renamed not receive a changelog note? | 05:41:10 |
 hexa | it didn't even make a release, sooo | 05:42:07 |
| hexa |
It's been long overdue, but Colmena 0.4.0 is finally here:
| 05:42:15 |
| hexa | I't s been long overdue, again | 05:42:21 |
| marshmallow changed their profile picture. | 05:52:57 |
| marshmallow | Oh, maybe I shouldn't be using main and assuming its stable. But the nixpkgs version appears to always break for me :( | 05:58:03 |
|  lgcl (she/they) changed their display name from lgcl (they/them) to lgcl (she/they). | 18:08:04 |

|  nope changed their display name from SS Bullshit Dreams to Corporate Cute. | 22:58:17 |

| tebriel | is there an equivalent of nix flake check for the colmena hive configurations? like flake check evaluates nixosConfigurations.<name>.config.system.build.toplevel | 00:20:58 |

The design is for the makeHive function control the evaluation so you're able to get config cross-reference via the nodes argument, apply a set of common modules, etc. There are ways to shove existing nixosConfigurations into colmenaHive though (see the issue on this) | 22:56:43 |

also, can colmena deploy standalone home-manager configuration? No, no such support yet. Some deploy-rs-style pluggable target support would be nice, but don't have the cycles at the moment | 22:57:54 |
