Editing Directory Structure

{{Welcome}}
{{Navbar System}}

==Introduction==

The Ghost/<q>FreeBSD directory hierarchy is fundamental to obtaining an overall understanding of the system. The most important directory is root or, “/”. This directory is the first one mounted at boot time and it contains the base system necessary to prepare the operating system for multi-user operation. The root directory also contains mount points for other file systems that are mounted during the transition to multi-user operation.</q>

A mount point is a directory where additional file systems can be grafted onto a parent file system (usually the root file system). This is further described in FreeBSD Handbook Section 3.6, [https://www.freebsd.org/doc/handbook/disk-organization.html “Disk Organization”]. 

See also [[Standard Mount Points]].


==Directory Structure==

At the first step we have to copy the Directory Structure from [https://www.freebsd.org/doc/handbook/dirstructure.html FreeBSD Handbook chapter: 3.5. Directory Structure] in the following table.
We use [https://www.freebsd.org/cgi/man.cgi?query=hier&sektion=7&manpath=freebsd-release-ports hier(7)] and compare this structure with the installed structure of GhostBSD on metal. This  [https://www.freebsd.org/cgi/man.cgi?query=hier&sektion=7&manpath=freebsd-release-ports manual page] documents	the default FreeBSD file system	layout,	but     the actual	hierarchy on a given system is defined at the system administrator's discretion.  A well-maintained installation will include a customized version of	this document.

By     default, they display the names, section numbers, and description lines    of	all matching manuals.
|-
|find(1)||The [https://www.freebsd.org/cgi/man.cgi?query=find&sektion=1&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports find] utility recursively descends the directory tree for each path     listed, evaluating	an expression (composed	of the "primaries" and     "operands"	listed below) in terms of each file in the tree.

|-
|fsck(8)||The [https://www.freebsd.org/cgi/man.cgi?query=fsck&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports fsck] utility invokes file system-specific programs to check the spe cial devices listed in the	fstab(5) file or in the	command	line for consistency.
