Can you tell me where did  ubuntu15.04 define the environment variables "UPSTART_SESSION"  ?

Hi,
 
You have asked a lot of questions already. Could you maybe elaborate
what are you investigating overall? Or what are you trying to achieve?
Answering questions one by one is not very productive.
 
UPSTART_SESSION variable points at private unix socket that one can
use to communicate with a user session upstart. When present in the
environment, initctl and other tools use that socket to talk to the
user upstart session.
 
Regards,
 
Dimitri.
