Be careful when touching process-global state when writing charm hooks. Calling out to the juju tools such as config-get will inherit the normal C environment, and juju may break in surprising ways if you don't leave it how you found it.
Yolanda had this problem today, when trying to use setuid in a script. What is the best way of handling that? For things like the working directory, just doing try/finally and reverting the value is fine, or in python invoking a subprocess in the desired location. To switch user, forking and waiting for the fork to complete seems safest?
