Major Description
I'm currently working on upgrading the RPM and DEB packaging for Apache Brooklyn. The project uses Karaf and has the following folder structure for the RPM package:
/- +- etc |+- brooklyn +- opt |+- brooklyn-0.12.0-SNAPSHOT ||+- bin ||+- data ||+- deploy ||+- lib ||+- system
The etc folder is not part of KARAF_HOME but in /etc/brooklyn. I setup my KARAF_ETC to point to this folder, however when I start Karaf, I get the followoing

As you can see, karaf expect the etc folder to be inside KARAF_HOME even though I specified my KARAF_ETC envvar.
If I softlink /etc/brooklyn to /opt/brooklyn-0.12.0-SNAPSHOT/etc, it works.
It's also worth mentioning that I don't have this issue with Karaf 4.0.8
