If you still have your local clone from before, and haven't made any (conflicting) changes, you can just 'cd' there and do 'git pull', then './install.sh'.
Otherwise you could make a completely new clone, but if you added any config files inside the old one, you'd have to copy them over to the new one.
I no changes, but yeah, I figured the configs would need to be backed up, as well as the log(s)... I keep the logs for analysis purposes... :) We'll see if I get this far today in the lab. Future , I will probably have to fork, and then figure out how to merge down changes to my fork as I need to make some changes in places, add some things in a couple areas for my specific needs, which appear to be already rejected upstream. git and compiling not my thing... I just updated my python stuff, and restart. :) No compilers needed. :) ;) Thanks.
