 All files and directories appear under the root_directory "/", even if stored on different physical devices.
-<note important>The location of all files and directories in Hyperbola comply with the Filesystem Hierarchy Standard (FHS), version 3.0, with the exception of **/usr/** that was removed. Therefore directories such as **/include/**, **/libexec/**, **/share/**, **/src/** and **/local/** were moved from **/usr/** to **/**.</note>

-**/bin/**
+<note>
+The term "essential" refers from all binaries, command binaries and libraries installed in folders located directly in the root directory, not inside /usr.
-Essential command executable (**bin**aries) for all users (e.g., cat, ls, cp)
+</note>
-(especially files required to boot or rescue the system)
-**/boot/**
-Boot loader, kernels and initrd files

-Temporarily **m**ou**nt**ed filesystems
-**/media/**
-Mount points for removable **media** such as CD-ROMs (appeared in FHS-2.3)
-**/opt/**
-Add-on application software packages
-Pre-compiled, non Hyperbola binary distribution (tar'ed..) goes here.
-  * /opt/bin/ : Same as for top-level hierarchy
-  * /opt/include/ : Same as for top-level hierarchy
-  * /opt/lib/ : Same as for top-level hierarchy
-  * /opt/sbin/ : Same as for top-level hierarchy
-  * /opt/share/ : Same as for top-level hierarchy
-**/proc/**
-Virtual filesystem documenting kernel and **proc**ess status, mostly text files (e.g., uptime, network)
-**/root/**
-Home directory for the **root** user

-(files required to boot or rescue the system)
-**/share/**
-Architecture-independent (**share**d) data
-**/src/**
-**S**ou**rc**e code (to build Hyperbola packages. see also /local/src/)
-**/srv/**
-Site-specific data which is **s**e**rv**ed by the system.
-**/sys/**
-**The** filesystem for exporting kernel objects.
-(many /proc/* files should have been here...)
-**/tmp/**
-**T**e**mp**orary files
-**/var/**
-**Var**iable data, such as logs, databases, websites, and temporary spool (e-mail..) files
