@Graeme-Miller That's one of the scenarios where adding a new line will
lead to unexpected results.
doing
```
export BROOKLYN_CFG_ADDITIONS="brooklyn.location.jclouds.aws-ec2.identity =
test_ident\nbrooklyn.location.jclouds.aws-ec2.credential = test_key"
echo $BROOKLYN_CFG_ADDITIONS
```
results in
```
brooklyn.location.jclouds.aws-ec2.identity =
test_ident\nbrooklyn.location.jclouds.aws-ec2.credential = test_key
```
So same thing repeated verbatim.
It's possible to get a new line out of it by using `printf
"BROOKLYN_CFG_ADDITIONS"`.
Wonder which one is better - failing early (when trying to serialise) or
escaping the new line. Current behaviour is worst - could easily be exploited.
Given this I'm inclined to merge the PR and then discuss improvements.
