- Eager-load all core autoloaded libraries if autoloads file isn't present. - Renames functions to be more descriptive of their true purpose: - doom-initialize-autoloads -> doom-load-autoloads-file - doom-load-env-vars -> doom-load-envvars-file - Use doom-module-p instead of featurep! for backend use (the latter is mainly syntax sugar for module use, and evaluates at compile/expansion time, which may cause hash-table-p errors early in the startup process). - Reorder plist library to prevent load order race condition with the functions using the macros that haven't been defined yet.

on Linux).

To generate a file, run `doom env refresh`. If you'd like this file to be

needs to be run once)."
