Nice!
Perhaps check if there really was an update, something like:
GIT_CHANGES=
git pull | wc -lif [ $GIT_CHANGES -gt 1 ]; then
kill, and then start
fi
So you can run this in test, qa, prod and not have e.g. prod restart if you push something
in dev-branch... (I assume the deploy hooks are run for all branches...)
