Fast emacs implementation with dump-emacs?

I came across this article about speeding up emacs startup.

I wanted to try, but I have segfault. Has anyone been able to do this for the latest versions of emacs?

Here is the makefile I am using:

emacs=/usr/local/bin/emacs fast-emacs: /usr/local/bin/emacs ~/.emacs $(emacs) -Q --batch -l "~/.emacs" \ --execute "(dump-emacs \"fast-emacs\" \"$(emacs)\")"

This trick stops working after emacs21, and dump-emacs now only works with bootstrap temacs to turn it into full-screen emacs. When emacs has been reset once, it cannot be reset again.

The site-init.el that the wiki refers to can do the trick, but I suspect you will encounter serious stability issues after you start including a bunch of packages in the image. All in all, it's not really worth it.

Another solution was published in Reddit if the linked page above does not work or does not work, and the proposed solution should be faster (launch time: 0.00 seconds).
