这是我的本来的最新的custom-file，我没有再用Spacemacs，而是用的purcell的配置，其实这里面并没啥内容
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(safe-local-variable-values
(quote
((checkdoc-minor-mode . t)
(mangle-whitespace . t)
(no-byte-compile t))))
'(session-use-package t nil (session)))
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(custom-group-tag ((t (:height 1.0)))))
然后这是每次都插进去的一摸一样的配置，插在 custom-set-variables 里面

明显是我之前使用Spacemacs 所残留下来的配置，然后Emacs机智地记住了，（不知道记在什么地方），然后每次我修改完一个variable以后点击save all 就插进去了。
然而最最灵异的事情在于，我完全找不到这段配置究竟在什么地方。Mac下使用mdfind(Spotlight)也找不到，然后Emacs已经重新编译了2次了，我的配置文件已经完全换新的了，然后cache文件我已经完全删掉过很多次了，然后elpa我也重新删掉重新装了，只不过旧的那个Spacemacs的配置我没舍得删，路径在 ~/.spacemacs.d/custom.el 内容很多，既有
'(hl-bg-colors

这种灵异事件中的，也有不在灵异事件中的其他配置。总共有200多行。
我的新配置中完全没有提到一点点 Spacemacs ，绞尽脑汁也想不出来Emacs是把过去很久之前的custom 信息保存下来的。而且还是选择性地记住了。
想问问大家有什么有效的排查手段，因为这个问题我绝对每次都能复现。
