Author: adietish Date: 2012-01-11 07:38:39 -0500 (Wed, 11 Jan 2012) New Revision: 37760 Modified: trunk/usage/plugins/org.jboss.tools.usage/src/org/jboss/tools/usage/googleanalytics/eclipse/LinuxSystem.java trunk/usage/tests/org.jboss.tools.usage.test/src/org/jboss/tools/usage/test/LinuxSystemTest.java Log: [JBIDE-10577] now set all linux distros with identical release files to check the content (RedHat/CentOS, Ubuntu/Mint). So no false positive possible for those. If none matches, I return "Unknown".
