2 NetworkManager Connection Profiles

Each network connection configuration that you create becomes a NetworkManager connection profile on the system. In Oracle Linux 8, profiles recognize both the key file format and the ifcfg format so that network scripts from previous Oracle Linux releases continue to work. However, network scripts are deprecated in Oracle Linux 8. If you manually create connection profiles, use the key file format instead.

Depending on its purpose, a NetworkManager connection profile can be stored in one of the following locations:

• /etc/NetworkManager/system-connections/: Default location of persistent profiles that are created by the user. Profiles in this directory can also be edited.
• /run/NetworkManager/system-connections/: Location of temporary profiles that are automatically removed when you reboot the system.
• /usr/lib/NetworkManager/system-connections/: Location of predeployed and permanent connection profiles. If you edit one of these profiles by using the NetworkManager API, then the profile is copied either to the persistent or the temporary directory.
