Hehehe, for what it's worth, I encountered one of those edge cases a few years ago. Dell OMSA, at least in the days of Centos 4, was distributed as a self-extracting binary, that would read the contents of /etc/redhat-release and compare it against a list of predefined strings, and then refused to operate. The workaround was to hack /etc/redhat-release. But anyway. That's pretty unusual. Thanks...
