How do I configure emacs to read custom-set-variables after startup

I found that emacs startup faster after I commented out the custom-set-variables section in init.el. I wonder if there is a proper way to tell emacs not to load it until emacs fully startup. Currently I add it to emacs startup hook, but I don't think it's the right way to do it, because every time I changed a setting through customize, emacs creates a new block of custom-set-variables instead of changing the one in the add-hook funtion. ​ Edit: add this line to your emacs config file. (setq custom-file (locate-user-emacs-file "custom_var.el")) ​

Read NEWS-28 on early-init :

I am not sure what exactly I have to look for in news 28, can you be more specific? thanks

Oh, thank you sir, it's working as intended. Much appreciated!!

If your OS is Linux, you may run systemd with Emacs. [https://emacsredux.com/blog/2020/07/16/running-emacs-with-systemd/](https://emacsredux.com/blog/2020/07/16/running-emacs-with-systemd/) :

Thanks for the information!

Set `C-h v custom-file` and then you can load it whenever you want to. I can't say that I understand how it's supposed to assist with your actual problem, but it achieves what you've actually asked for.

Thanks! This did the trick

To load `custom-file` until emacs fully startup, you may want to consider `emacs-startup-hook`, that would be (altogether): ``` (add-hook 'emacs-startup-hook (lambda () (load custom-file))) ```

Ya, I know this method. But there is a downside that emacs will look ugly while it's loading packages and other stuff

I see. I had all my ui stuff in `lisp/init-ui.el` instead of putting all my configs in `custom.el` (assuming that might be what you have done, if I had guessed correcly) Since some point, I have fully moved from using `custom.el` at all, but of course emacs still put custom-set-variables here anyways.
