[systemd-devel] Kill on console works, ExecStop not

[Florian Lindner]

Hello,

I have a systemd 224 user service unit that starts the emacs daemon:

[Unit]
Description=Emacs: the extensible, self-documenting text editor

[Service]
Type=forking
ExecStart=/usr/bin/emacs --daemon
ExecStop=/usr/bin/emacsclient --eval "(progn (setq kill-emacs-hook nil) 
(kill-emacs))"
Restart=always

[Install]
WantedBy=default.target


I starts just fine, but stopping is problematic:

% systemctl --user start emacs

However, stopping with the same command works:

% /usr/bin/emacs --daemon                                                                                                                                                                                               
[...]
% /usr/bin/emacsclient --eval "(progn (setq kill-emacs-hook nil) (kill-
emacs))"

returns 0 exit code.

Since emacs --daemon returns to the shell after executing I think 
Type=forking is correct.

I'm unsure if it's a configuration problem on my unit or if it's just the 
way emacs works and I should add SuccessExitStatus=15.

Thanks,
Florian
