I think I've now fixed the bug where build operation in FLI would fail after the Fedora server was found not to have restarted yet upon creating the gsdl.xml file in the fedora/tomcat/conf/Catalina/localhost folder. The problem, it turns out, was that the tries and wait-retry args to wget would not retry if a connection is refused or a page not found is returned, and at times this would happen the very first time wget tried to access the Fedora server to check whether it was running, so it wouldn't retry anymore.
