   The Solaris code that does that is called dldump() and was
invented years ago (~25 years?) to support emacs. We used to
get occasional bug reports about emacs not dumping from time
to time, and dldump() put an end to that.

I'm the person who maintains that code in Solaris, and also the
person who packages Emacs for our platform. We stopped using the
unexec code the moment the portable dumper arrived, and haven't
looked back. I don't think we'd even notice if unexec() went away.

There are open source variants of Solaris for whom I don't
speak, but from what I know about our common code, they should
not be any more stuck on unexec() than we are. pdumper really
doesn't use any unix features that didn't exist decades ago.

Thanks for caring, but don't let us slow this down. The portable
dumper is The Way.
