Root Filesystem - ArrowElectronics/data-storm-daq GitHub Wiki
The root filesystem is the filesystem that is contained on the same partition on which the root directory is located, and it is the filesystem on which all the other filesystems are mounted (i.e., logically attached to the system) as the system is booted up (i.e., started up)
