In cases where we want to install config files to an alternate location (say TRAF_CONF=/etc/trafodion), we would copy all the default files from TRAF_HOME/conf to TRAF_CONF and make modifications in the TRAF_CONF location. In development workspace, both locations can be one in the same. One case where I left the original path is for the install_features file. This file identifies version features and is not a user-configurable file. Hence it should be read from the TRAF_HOME/conf location.
