3.2.2.4 Image/rootfs
Linux adopts a hierarchical file system (HFS). Image/rootfs is the Linux file system at
the highest level of the file structure, similar to the trunk of a tree. The subdirectories
are branches, and the files inside these subdirectories are the leaves. Image/rootfs
contains all the subdirectories and files used by the file system, which is why it is
known as the root of the entire file system.
The main folders in “rootfs” are listed below.
“cross_compiler”
