Zenoss 5: How to modify zenhub container

Hey guys,

I've already asked this question during the dev hours a couple of days ago, but I wanted to make sure that I get an official answer + that this answer will be available to others as well.

So what is the official way to modify the zenhub container in Zenoss 5

The reason why I'm asking is that my ZenPack requires an external package to be installed and available to zenhub for modeling and performance monitoring.

Based on rockets recommendation I've used the following method:
serviced service shell -s -i zenhub bash

exit
serviced snapshot commit

So far this seems to be working fine and also after a full reboot of the OS the changes are not getting lost.

But is this the way it should be done Or am I going to have problems during an upgrade of Zenoss

Please let me know.

Thanks.
