Rootfs (Root File System)

The Linux root file system is usually thought of in a tree structure. The tree of the
file system starts at the trunk or slash, indicated by a forward slash (/). This directory,
containing all underlying directories and files, is also called the root directory or
"the root" of the file system.
Directories that are only one level below the root directory are often preceded by a
slash, to indicate their position and prevent confusion with other directories that
could have the same name. When starting with a new system, it is always a good
idea to take a look in the root directory.
The "rootfs" contains these main folders:
- bin Common programs, shared by the system, the system administrator and
the users.
- boot The startup files and the kernel. In some recent distributions also grub
data. Grub is the GRand Unified Boot loader and is an attempt to get rid of
the many different boot-loaders we know today.
- dev Contains references to all the CPU peripheral hardware, which are
