I have two servers, they're identical (I believe), production and staging servers.

And I have upstart script in /etc/init/ folder.

description "Discoure process"



setuid deploy

setgid deploy



respawn

respawn limit 3 30



start on runlevel [2345]

stop on runlevel [06]



script

exec /bin/bash <<'EOT'

  echo "$HOME/.rbenv"



  cd /home/deploy/discourse/current



  bundle exec bluepill load config/discourse.pill --no-privileged --base-dir tmp/bluepill --logfile log/bluepill.log

EOT

end script

On the staging server it works well, but when I'm running that script on production server then the HOME variable is empty, the code echo "$HOME/.rbenv" is evaluating to "/.rbenv"

What might be a problem here? Thanks
