Zhaofeng Li: How did you determine that the change in e58dde1be08cf7fbac7299e928b6d0e143edbec9 would fix #50? Like, what was your debug process?

Then I added traces to the split docs build process in documentation.nix, and found out that it was trying to do a removePrefix on the full module paths using modulesPath, and remembered that I was explicitly setting modulesPath in Colmena

In reply to @winterqt:nixos.dev
got it -- why were you setting it in the first place, anyways?

In reply to @winterqt:nixos.dev
does Colmena add much overhead to the underlying things it does? or does speed depend on build speed + ssh connection latency + multiple ssh connection handshakes (unless you use ControlMaster)?

I do appreciate you pointing out that you perceived it as rude 🙂 It helps me improve how I communicate as a non-native speaker
