     /bin/    User utilities fundamental to both single and multi-user envi-
              ronments.  These programs are statically compiled and therefore
              do not depend on any system libraries to run.

     /bsd     Pure kernel executable (the operating system loaded into memory
              at boot-time).

     /dev/    Block and character device files.

              MAKEDEV  Script for creating device files (see makedev(8)).
              fd/      File descriptor files (see fd(4)).

     /emul/   Base directory for alternate areas searched first when system
              call emulation is in effect (see compat_bsdos(8),
              compat_freebsd(8), compat_ibcs2(8), compat_linux(8),
              compat_sunos(8), compat_svr4(8), compat_ultrix(8)).

     /etc/    System configuration files and scripts.

     /home/   Default location for user home directories.

     /mnt/    Empty directory commonly used by system administrators as a tem-
              porary mount point.

     /root/   Default home directory for the superuser.

     /sbin/   System programs and administration utilities fundamental to both
              single and multi-user environments.

     /stand/  Programs used in a stand-alone environment.

     /tmp/    Temporary files, usually an mfs(8) memory-based filesystem (the
              contents of /tmp are usually not preserved across a system re-
              boot).

     /usr/    Contains the majority of user utilities and applications.

              X11R6/    Files required for the X11 window system.
