Currently, install.sh provide a way to customize sysconfig directory, but sysconfig directory is hardcoded on script. Also, /etc/sysconfig seems correct to use default value, but current code specify /etc/default as non-redhat distributions. Instead of hardcoding, generate generate python script in install.sh to save specified sysconfig directory path in python code.
