As previously mentioned on the mailing list I think this is a useful
feature for testing. It also means you can screw up any configs and
databases in the new "alternative" firmware directory without killing
your stable working setup.

Currently you have to manually faff around with the fullzip file as it
contains the same hard-coded path. I'll look into it next time.
