+[b]How do I reinstall an existing hub on the same server?[/b]
+
+1) [code]git reset --hard HEAD[/code] will reset all files to their upstream defaults.  This will not reset any local files that do not also exist upstream.  Eg, if you have local changes to mod/channel.php, this will reset them - but will not reset any changes in mod/site/channel.php
+2) If you absolutely must reinstall - for example, if you need to upgrade operating system - follow the steps for moving to a different server, but instead of using rsync, backup and restore some other way.
+
+Do not reinstall a hub with a fresh database and fresh .htconfig.php unless as a very last resort.  Creating a temporary account and ask for help via a support channel for non-trivial reinstalls is preferable to reinstalling fresh.
