what is MANAGE_BUILTINS=no ? ChatGPT: ChatGPT The MANAGE_BUILTINS=no setting in the /etc/default/ufw configuration file controls whether UFW manages certain built-in application profiles automatically. Here’s a bit more detail:

Explanation of MANAGE_BUILTINS Purpose: When set to yes, UFW automatically manages its built-in application profiles (like OpenSSH, Nginx, etc.) and makes them available for use with the ufw app commands.

Setting to no: If you set MANAGE_BUILTINS=no, UFW will not automatically manage or include these built-in profiles. This is useful in specific scenarios where you want to define your own profiles or prevent automatic modifications.

Example Configuration In the /etc/default/ufw file, it might look like this:

Simplicity: In some cases, if you're not using application profiles at all, you might choose to disable this feature for simplicity. Impact If you set MANAGE_BUILTINS=no, you will not be able to use the predefined application profiles that UFW comes with, so you'll need to create your own profiles if needed.
