I'm running dbsql in production, and want to run a test instance on the same host, but entirely separate from the running thing in /opt/gt, and writing to a different MySQL database name. Is there an easy way to do this, short of creating two separate chroot jails or otherwise faking out the existence of two hosts?

Just copying everything from /opt/gt to /opt/gt-test and starting to tweak some configuration files, I discovered that they are still linked together (reconfiguring the test instance to use a different database changed the setting on the live one!). I'm not eager to go hunt down all the places I'd need to hack. There must be an easier way to do this.
