If you keep this here, in addition with the condition ```if [ ${CURRENT_OS} == "${OS_OTHER}" ];``` in the install.sh script, CentralReport installer will accept to start the installation procedure on a RedHat distribution (and some unexpected behaviors).

Just an idea to improve this function:
```
function getOS(){

    CURRENT_OS=${OS_OTHER}

    if [ $(uname -s) == "Darwin" ]; then
        CURRENT_OS=${OS_MAC}
    elif [ -f "/etc/debian_version" ] || [ -f "/etc/lsb-release" ]; then
        CURRENT_OS=${OS_DEBIAN}
    elif [ -f "/etc/redhat-release" ]; then
        OS=`cat /etc/redhat-release | awk {'print $1'}`
        if [ ${OS} == "CentOS" ]; then
            CURRENT_OS=${OS_CENTOS}
        fi
    fi
}
```
