What happens to the contents of the /tmp directory upon system reboot?

The contents of the /tmp directory are typically cleared out upon system reboot. This behavior is based on the purpose of the /tmp directory, which is designed for temporary file storage. It serves as a space where applications can write temporary data that does not need to persist after a reboot. Therefore, once the system is restarted, this directory is often emptied to free up space and remove any temporary files that are no longer needed, ensuring that the system starts in a clean state.

This automatic cleanup process helps reduce clutter and potential security issues associated with residual temporary files left by applications. It’s important to know how this directory is handled, especially in scenarios where applications rely on temporary file storage for performance or operation.
