Glenn, than you very much for responding to this and reopening the bug
(I was going to reopen as well).  The issue is as you describe.  There
should at least be a way to operate the emacs server such that it
does not fork, but just runs in a "headless" mode, with logs to stderr.
This is the "new-style" that you're referring to, that is how all modern
init systems handle daemons.

Thanks for the consideration.

jamie.
