# cat /etc/sysconfig/network-scripts/readme-ifcfg-rh.txt NetworkManager stores new network profiles in keyfile format in the /etc/NetworkManager/system-connections/ directory.

By default, NetworkManager no longer creates new profiles in this format. Connection profiles in keyfile format have many benefits. For example, this format is INI file-based and can easily be parsed and generated. ... |
