I'm currently trying to patch Configure to tell you the Linux distribution (RedHat, SuSE, Debian, others as folks supply the information), and I'm unsure of how to best parse RedHat's /etc/redhat-release file. I have the following 1 example: Red Hat Linux release 6.1 (Cartman) I'm guessing that the '6.1' is what would be most useful. Does anyone have a variety of Red Hat systems around or enough familiarity with Red Hat to say how stable that format is or give me other examples?
