NetworkManager stores new network profiles in keyfile format in the
/etc/NetworkManager/system-connections/ directory.
Previously, NetworkManager stored network profiles in ifcfg format
in this directory (/etc/sysconfig/network-scripts/). However, the ifcfg
format is deprecated. 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.
