Can't complete Edit Predictions Onborading on NixOS

[danielgafni]

Summary

I am running NixOS and am trying to enable Edit Predictions in Zed.

I have "show_edit_predictions": true in my Zed config.

However, they do not show up. I suspect this is because I can't complete the on-boarding dialog where the terms of service must be accepted:

2025-03-05T11:55:59.770457298+02:00 [ERROR] Failed to write settings to file "/nix/store/fxg55jr0w81x1iz5yimniygqdgj57zrw-zed-user-settings"

Caused by:
    Read-only file system (os error 30) at path "/nix/store/.tmpZlR4UK"

This is an ongoing issue with Zed on NixOS, it appears in different forms whenever Zed is trying to edit files in the installation directory. Also see: #24537

I suggest alternative files which are guaranteed to be owned by the user (such as $XDG_DATA_HOME) to be used instead.

P.S. Not sure what exactly is Zed trying to write, is this the show_edit_predictions setting?
I've tried to look into the code but only found a write to the sqlite database.
