relatime: The kernel is using an optimized scheme to record file access and modification meta-data.rw: The file system is readable and writable.On this test computer, there is a single ext4 file system, it is on device sda-the first storage device mounted, usually the main hard drive-and mounted on /, which is the root of the file system tree. We’ve also issued a command to list ext4 file systems.

You’ll want to substitute the tmpfs parameter for the file type in which you are interested. A tmpfs file system appears as though it were a regular, mounted file system but it is actually stored in volatile memory-the tmp stands for temporary-instead of on a persistent storage device.
