Actually I have a bash script for testing my dot emacs without any
external package:
--8<---------------cut here---------------start------------->8---
emacs --no-bitmap-icon -Q --eval " (progn (defvar
my-cli-not-init-pkgs-flag t \"v=how emacs start\") (load
\"~/.emacs.d/init.el\") )"
--8<---------------cut here---------------end--------------->8---

See the result (with external packages isolated):
--8<---------------cut here---------------start------------->8---
