where to start emacs --deamon in debian?

[Jonas Stein]

Hi 
what is the best way to start emacs --deamon in a debian (testing) system?
Should i put it in a selfmade init script to /etc/init.d or into /etc/profiles 
or some elsewhere?

kind regards,
Jonas

A system file is not the appropriate choice (you won't own the  
process). A script which is executed at your (personal) login time is  
more suitable – but it must not launch GNU Emacs whenever a login  
shell is initiated! This can be achieved by checking before whether  
GNU Emacs is running, whether an environment variable is set (set when  
GNU Emacs was launched as daemon the first time), whether a semaphore  
file exists (created when GNU Emacs was launched as daemon the first  
time)...

I do this in .bash_profile for the users who I wish to set this up for:

if ! killall -q -s 0 emacs ; then
  emacs --daemon
fi

I agree with the prior posts re: not starting the process via system init
files!  The wiki has an article on doing just that if you must.  Personally
I've got (server-start) in my .emacs and thereafter every file is opened
with the client.

Only if you issue emacsclient as the command. However, there is no need
with emacs 23 to specifically do a server start. Just set your editor
env to something like "edit" where edit is a small bash script like
this:-

,----
| #!/bin/bash
| # edit
| export GDK_NATIVE_WINDOWS=1
| exec emacsclient --alternate-editor="" -c "$@"
`----

NB: the export is to get around a menu bug in emacs 23.

In my .bash_env I have

,----
| export EDITOR="~/bin/edit"
`----

Since you need to emacsclient anyway if you specifically do a
server-start then you might as well issue "edit" or whatever you want it
to be and let emacs take care of it. If the daemon is not running it
automatically starts it for you.

I suggest using emacsclient with -a '' option. It connects to the daemon
or starts it if it's not running already. For example, I have Bash alias

    alias em="emacsclient -t -a '' --"

and my KDE has a shortcut key which executes command

    emacsclient -c -n -a ''

Yep, thats the way to do it IMO. No hassles with scripting to ensure it
isn't already running, no complications with issues in your .emacs
screwing up your startup scripts etc. Nice and simple and easy to
maintain and lets emacs to all the heavy lifting!

don't do it as a /etc/init.d script. This overly complicates things and
buys you very little. Remember that emacs daemon mode is not designed to
be a multi-user daemon, its a user daemon. 

My advice would be to put it in your ~/.bash_profile or ~/profile or
whatever script is run by your shell when you login. Another
alternative, if you run X, wold be to put it in your X startup script
(depends on what X environment your running). Just ensure your code
checks to make sure its not already running before you start it.

I find all such setups more hassle to setup and maintain than benefits
they provide. I just use emacsclient when I want an emacs
frame and have it setup such that if emacs is not running, it will start
it up in daemon mode. I'm runing the CVS version and this seems to be
the efault behavior anyway, but I'm not sure if that is also the case
with the released version.
