The Linux Assigned Names and Numbers Authority (LANANA) is a central registry of names and numbers used within Linux.It was created in 2000 by H. Peter Anvin.As of 2013, it along with Filesystem Hierarchy Standard matters had moved under the Linux Standard Base, which itself operates under Linux Foundation's auspices per Russ Herrold.
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
The criticism of Linux focuses on issues concerning use of operating systems which use the Linux kernel. While the Linux-based Android operating system dominates the smartphone market in many countries, [1] [2] and Linux is used on the New York Stock Exchange and most supercomputers, [3] it is used in few desktop and laptop computers.

Some operating systems restrict a user's access only to their home directory or project directory, thus isolating their activities from all other users. In early versions of Unix, the root directory was the home directory of the root user , but modern Unix usually uses another directory such as /root for this purpose.
The setuid permission set on a directory is ignored on most UNIX and Linux systems. [ 5 ] [ citation needed ] However FreeBSD can be configured to interpret setuid in a manner similar to setgid , in which case it forces all files and sub-directories created in a directory to be owned by that directory's owner - a simple form of inheritance.

View of the root directory in the OpenIndiana operating system. In a computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most directory in a hierarchy. [1] It can be likened to the trunk of a tree, as the starting point where all branches originate from.
When a process refers to a file using a path that does not begin with a / (forward slash), the path is interpreted as relative to the process's working directory. So for example a process with working directory /rabbit-shoes that asks to create the file foo.txt will end up creating the file /rabbit-shoes/foo.txt.
