Updating Discovery "Linux - Distribution" probe to account for Debian

[henrydoan]

To update the Discovery "Linux - Distribution" probe to account for Debian hosts, add the following to the probe's post processor script (addition highlighted in blue):

...

        else if (lowercaseOutput.indexOf('centos') != -1) {

                  current.os = "Linux CentOS";

                  versionMatch = /release ([0-9\.]+)/.exec(lowercaseOutput);

        }

        else if (lowercaseOutput.indexOf('ubuntu') != -1) {

                  current.os = "Linux Ubuntu";

                  versionMatch = /version="([0-9\.]+)/.exec(lowercaseOutput);

        }

        else if (lowercaseOutput.indexOf('debian') != -1) {

                  current.os = "Linux Debian";

                  versionMatch = /debian \\m ([0-9\.\-]+)/.exec(lowercaseOutput);

        }

        else {

                  current.os = "GNU/Linux";

        }

        if(versionMatch && versionMatch[1])

                  current.os_version = versionMatch[1];

  },

  type: "ProbePostProcessor"

});

The corresponding probe parameter also required (Debian generally has a /etc/issue file instead of /etc/*release):

#!/bin/sh

if [ -f /etc/*release ]; then

        cat /etc/*release

else

        cat /etc/issue
