Apparently the FAH client requires that there be no spaces between the = sign and the userid in the config file. Apparently the client code sees the space and prepends an underscore to the userid. This results in the stats for the Gentoo FAH participants being applied to the wrong id and loss of bragging rights, etc that comes with those stats. I've managed to track down the following: /etc/init.d/foldingathome start runs copy_client_config which uses Pythons ConfigParser::write which has the following line of code: fp.write("%s = %s\n" % (key, str(value).replace('\n', '\n\t'))) Which I believe is the line that's introducing the spaces.
