C.2. The Directory Tree

Debian GNU/kFreeBSD adheres to the Filesystem Hierarchy Standard for directory and file naming. This standard allows users and software programs to predict the location of files and directories. The root level directory is represented simply by the slash /. At the root level, all Debian systems include these directories:

Directory Content
bin Essential command binaries
boot Static files of the boot loader
dev Device files
etc Host-specific system configuration
home User home directories
lib Essential shared libraries and kernel modules
media Contains mount points for replaceable media
mnt Mount point for mounting a file system temporarily
proc Virtual directory for system information (2.4 and 2.6 kernels)
root Home directory for the root user
run Run-time variable data
sbin Essential system binaries
sys Virtual directory for system information (2.6 kernels)
tmp Temporary files
usr Secondary hierarchy
var Variable data
srv Data for services provided by the system
opt Add-on application software packages

The following is a list of important considerations regarding directories and partitions. Note that disk usage varies widely given system configuration and specific usage patterns. The recommendations here are general guidelines and provide a starting point for partitioning.
