Fast emacs executable with dump-emacs? -

i came across article speeding emacs startup.

i wanted try it, segfault. has managed recent emacs versions?

here's makefile i'm 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 stopped working sometime after emacs21, , dump-emacs works bootstrap temacs turn full-blown emacs. when emacs has been dumped once, can't dumped again.

the site-init.el trick referenced on wiki might trick, suspect you're going run serious stability problems once start including bunch of packages in image. in all, not worth it.
