Why does stopping user shepherd kill my Emacs and how I make it to stop?

Why does stopping user shepherd kill my Emacs and how I make it to stop?

Hi,

today I noticed that when I stop my user shepherd (`herd stop root'), it
kills my Emacs instance.  I would like to point out that the Emacs
daemon is *not* managed by the Shepherd, I just start it using the
following in the `init.el':

--8<---------------cut here---------------start------------->8---
(require 'server)

(or (server-running-p)
    (server-start))
--8<---------------cut here---------------end--------------->8---

I do not have many user shepherd services:

--8<---------------cut here---------------start------------->8---
Started:
 + dbus
 + pulseaudio
 + root
 + ssh-agent
--8<---------------cut here---------------end--------------->8---

Emacs does not log anything into the terminal regarding the termination
cause, and shepherd does not mention anything at all.  Here is full log
from shepherd start to termination:

--8<---------------cut here---------------start------------->8---
Starting service root...
Service root started.
Service root running with value #t.
Service root has been started.
WARNING: Use of `load' in declarative module (#{ g107}#).  Add #:declarative? #f to your define-module invocation.

Stopping service root...
Stopping service ssh-agent...

Service ssh-agent is now stopped.
Stopping service pulseaudio...
Service pulseaudio stopped.
Service pulseaudio is now stopped.
Stopping service dbus...
Service dbus stopped.
Service dbus is now stopped.
Exiting.
--8<---------------cut here---------------end--------------->8---

Would anyone be able to advice why this is happening (or at least how to
find out)?  And, more importantly, how do I prevent this?  I do *not*
want my Emacs coupled to my user shepherd.

Thanks a lot,
Tomas

I have no idea, but did you try stopping the services one by one? It might not be the shepherd killing your Emacs, it might be your Emacs crashing because dbus (or something) is suddenly gone.
