It is possible to make that error message a little more descriptive
with the following patch on startup.el:
*** ed:[orig.lisp]startup.el
--- ed:[new.lisp]startup.el
**************
*** 124,130
;; Don't you dare turn this off for anyone
;; except yourself.
(load "default" t t)))))
! (error (message "Error in init file")))
(if (get-buffer "*scratch*")
(save-excursion
(set-buffer "*scratch*")
--- 124,130 -----
;; Don't you dare turn this off for anyone
;; except yourself.
(load "default" t t)))))
! (error (message (format "Error in init file: %s" error))))
(if (get-buffer "*scratch*")
(save-excursion
(set-buffer "*scratch*")
The message can be a little cryptic, but it helps to get the message:
"Error in init file: (void-variable foo)"
