Yes, in principle.  I think there was a bug last time I tried, but I
have done it.  The SCM scheme system, for instance, also does this
(with caveats) via unexec and might be a better example.  (This might
well not be the best technique to dump and restore an Erlang system if
that was really wanted.)

See C-h f dump-emacs

Sorry.  A web search found no relevant mentions in an Erlang context,
which surprised me; hence the question.  Can one read about it
somewhere?
