@Stefano & @RequestedDeletion: if I can't get this resolved here shortly and have to proceed with a fresh reinstall + manual reconfig, how do I lift out old configs such as port forwards and dns name / dhcp ip lease assignments? Is this in mysql or in a text file or flat db somewhere? I was hunting a bit, but found nothing more than log entries so far for some of the hostname assignments.
As per HSF above, most settings should be stored in text files in /home/e-smith/db
However, you CANNOT just copy those over and expect them to work - but you can use them for reference.
A shame we can't get to the bottom of this is your time frame - might have been better if you had reported all of the info on the bug tracker as some devs don't read much in here.
If you keep your original backup, is there a chance that you can try and restore to a test server to try and replicate the issue so it can be looked at ? If so, follow up with a précis of the notes here on your bug.
