[systemd-devel] About systemd call dbus session bus

[张洋]

Hi all

I've got a problem here:

When my system setup I need to execute a shell script to export dbus
session address, the script as follows:

#!/bin/sh
rm /tmp/session_amgr
dbus-daemon --session --print-address --fork > /tmp/session_amgr
export DBUS_SESSION_BUS_ADDRESS=`cat /tmp/session_amgr`

And I have an app in folder /geniviLife, it will export interfaces in
session bus.  When I run the app manually, it works.
However, when I tried to start it using systemd, it failed. It seems
systemd didn't read the export env? Here is the log:
