Depending on the used kernel configuration some of these API file systems might not be available and others might exist instead. As these interfaces are important for kernel-to-userspace and userspace-to-userspace communication they are mounted automatically and without configuration or interference by the user. Disabling or changing their parameters might hence result in applications breaking as they can no longer access the interfaces they need. Even though the default settings of these file systems should normally be suitable for most setups, in some cases it might make sense to change the mount options, or possibly even disable some of these file systems. |
