23 .TH FILESYSTEM 5 "Jan 20, 2018"
24 .SH NAME
25 filesystem \- File system organization
26 .SH SYNOPSIS

37 .SH DESCRIPTION
38 .LP
39 The file system tree is organized for administrative convenience. Distinct
40 areas within the file system tree are provided for files that are private to
41 one machine, files that can be shared by multiple machines of a common
42 platform, files that can be shared by all machines, and home directories. This
43 organization allows sharable files to be stored on one machine but accessed by
44 many machines using a remote file access mechanism such as \fBNFS\fR. Grouping
45 together similar files makes the file system tree easier to upgrade and manage.
46 .sp
47 .LP
48 The file system tree consists of a root file system and a collection of
49 mountable file systems. The \fBmount\fR(2) program attaches mountable file
50 systems to the file system tree at mount points (directory entries) in the root
51 file system or other previously mounted file systems. Two file systems, \fB/\fR
52 (the root) and \fB/usr\fR, must be mounted and \fB/var\fR must be accessible to
53 have a functional system. The root file system is mounted automatically by the
54 kernel at boot time; the \fB/usr\fR file system is mounted by the system
55 start-up script, which is run as part of the booting process. \fB/var\fR can be
56 mounted as its own file system or be part of \fB/usr\fR, as it is by default.
57 .sp
58 .LP
59 The following descriptions make use of the terms \fBplatform\fR,
60 \fBplatform-dependent\fR, \fBplatform-independent\fR, and
61 \fBplatform-specific\fR. Platform refers to a machines Instruction Set
62 Architecture or processor type, such as is returned by \fBuname\fR \fB-m\fR.
63 \fBPlatform-dependent\fR refers to a file that is installed on all platforms
64 and whose contents vary depending on the platform. Like a platform-dependent
65 file, a \fBplatform-independent\fR file is installed on all platforms. However,
66 the contents of the latter type remains the same on all platforms. An example
67 of a platform-dependent file is compiled, executable program. An example of a
68 platform-independent file is a standard configuration file, such as
69 \fB/etc/hosts\fR. Unlike a platform-dependent or a platform-independent file,
70 the \fBplatform-specific\fR file is installed only on a subset of supported
71 platforms. Most platform-specific files are gathered under \fB/platform\fR and
72 \fB/usr/platform\fR.
