First, here is the appearance of the file server as it appears before any mounts or bindings. .TF /sys/src/cmd
/ The root directory.
/adm The administration directory for the file server.
/adm/users List of users known to the file server; see users (6).
/adm/keys Authentication keys for users.
/adm/netkeys SecureNet keys for users; see securenet (8).
/adm/timezone Directory of timezone files; see ctime (2).
/adm/timezone/EST.EDT Time zone description for Eastern Time. Other such files are in this directory too.
/adm/timezone/timezone Time zone description for the local time zone; a copy of one of the other files in this directory.
/bin
/dev
/env
/fd
/net
/proc
/srv
/tmp All empty unwritable directories, place holders for mounted services and directories.
/mnt A directory containing mount points for applications.
/n A directory containing mount points for file trees imported from remote systems.
/68020
/386
/sparc
/960
/mips Each CPU architecture supported by Plan 9 has a directory in the root containing architecture-specific files, to be selected according to $objtype or $cputype (see 2c (1) and init (8)). Here we list only those for /mips .
/mips/init The initialization program used during bootstrapping; see init (8).
/mips/bin Directory containing binaries for the MIPS architecture.
etc. Subdirectories of /mips/bin containing auxiliary tools and collecting related programs.
/mips/lib Directory of object code libraries as used by vl (see 2l (1)).
/mips/include Directory of MIPS-specific C include files.
/mips/9* The files in /mips beginning with a 9 are binaries of the operating system.
/mips/mkfile Selected by mk (1) when $objtype is mips , this file configures mk to compile for the MIPS architecture.
/rc Isomorphic to the architecture-dependent directories, this holds executables and libraries for the shell, rc (1).
/rc/bin Directory of shell executable files.
/rc/lib Directory of shell libraries.
/rc/lib/rcmain Startup code for rc (1).
/lib Collections of data, generally not parts of programs.
/lib/bible The King James edition
etc. Databases.
/lib/ndb The network database used by the networking software; see ndb (6) and ndb (8).
/lib/namespace The file used by newns (see auth (2)) to establish the default name space; see namespace (6).
/lib/font/bit Bitmap font files.
/lib/font/hershey Vector font files.
/sys System software.
/sys/include Directory of machine-independent C include files.
/sys/include/alef Directory of ALEF include files.
/sys/lib Pieces of programs not easily held in the various bins .
/sys/lib/acid Directory of acid (1) load modules.
/sys/lib/troff Directory of troff (1) font tables and macros.
/sys/lib/yaccpar The yacc (1) parser.
/sys/doc Other system documentation.
/sys/log Log files created by various system services.
/sys/src Top-level directory of system sources.
/sys/src/cmd Source to the commands in the bin directories.
/sys/src/9 Source to the operating system for terminals and CPU servers.
/sys/src/fs Source to the operating system for file servers.
/sys/src/lib* Source to the libraries.
/sys/src/alef Source for ALEF compilers and libraries.
/sys/src/alef/lib Source for ALEF libraries.
/mail Directory of electronic mail; see mail (1).
/mail/box Directory of users' mail box files.
/mail/lib Directory of alias files, etc.
/acme Directory of tools for acme (1).
/cron Directory of files for cron (8).
The following files and directories are modified in the standard name space, as defined by /lib/namespace (see namespace (6)). .TF /sys/src/cmd
/ The root of the name space. It is a kernel device, root (3), serving a number of local mount points such as /bin and /dev as well as the bootstrap program /boot . Unioned with / is the root of the main file server.
/boot Compiled into the operating system kernel, this file establishes the connection to the main file server and starts init ; see boot (8) and init (8).
/bin Mounted here is a union directory composed of /$objtype/bin , /rc/bin , $home/$objtype/bin , etc., so /bin is always the directory containing the appropriate executables for the current architecture.
/dev Mounted here is a union directory containing I/O devices such as the console ( cons (3)), the bitmap display ( bit (3)), etc. The window system, 8½ (1), prefixes this directory with its own version, overriding many device files with its own, multiplexed simulations of them.
/env Mounted here is the environment device, env (3), which holds environment variables such as $cputype .
/net Mounted here is a union directory formed of all the network devices available.
/net/cs The communications point for the connection server, ndb/cs (see ndb (8)).
/net/udp Directories holding the IP protocol devices (see ip (3)).
/net/dk A directory holding the Datakit protocol devices (see dk (3)).
/proc Mounted here is the process device, proc (3), which provides debugging access to active processes.
/fd Mounted here is the dup device, dup (3), which holds pseudonyms for open file descriptors.
/srv Mounted here is the service registry, srv (3), which holds connections to file servers.
/srv/boot The communication channel to the main file server for the machine.
/mnt/8½ Mount point for the window system.
/mnt/term Mount point for the terminal's name space as seen by the CPU server after a cpu (1) command.
/n/kremvax A place where machine kremvax 's name space may be mounted.
/tmp Mounted here is each user's private tmp, $home/tmp .
