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"))

If your OS is Linux, you may run systemd with Emacs.

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.
