/ (The root directory) - Amazon Linux 2023
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

/ (The root directory)

By default, AL2023 images are configured with a writable /, allowing privileged users to create new files and directories.

It is possible to configure systemd services to use a different path or image to appear as / for that service, as well as place access restrictions on any path.

Note

It is best practice for systemd services to be configured to restrict what the service has access to. This can include using the ReadOnlyPaths=/ directive which makes / read only for that service.

For more information on using systemd to restrict what access a service has to the system, see the systemd.exec(5) man page.
