       namespace - structure of conventional file name space


       After  a user's profile has run, the file name space should adhere to a
       number of conventions if the system is to behave normally.  This manual
       page  documents	those conventions by traversing the file hierarchy and
       describing the points of interest.  It also serves as a guide to	 where
       things  reside  in  the	file system proper.  The traversal is far from

       First, here is the appearance of the file server as it  appears	before
       any mounts or bindings.

       /      The root directory.

       /adm   The administration directory for the file server.

	      List of users known to the file server; see users(6).

	      Authentication keys for users.

	      SecureNet keys for users; see securenet(8).

	      Directory of timezone files; see ctime(2).

	      Time zone description for Eastern Time.  Other such files are in
	      this directory too.

	      Time zone description for the local time zone; a copy of one  of
	      the other files in this directory.








       /tmp   All empty unwritable directories, place holders for mounted ser‐
	      vices and directories.

       /mnt   A directory containing mount points for applications.

       /n     A directory containing mount points for file trees imported from
	      remote systems.








       /sparc 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 8c(1) and init(8)).  Here
	      we list only those for /386.

	      The  initialization  program  used  during  bootstrapping;   see

	      Directory containing binaries for the Intel x86 architecture.



       etc.   Subdirectories  of  /386/bin containing auxiliary tools and col‐
	      lecting related programs.

	      Directory of object code libraries as used by 8l (see 8l(1)).

	      Directory of x86-specific C include files.

	      The files in /386 beginning with a 9 are binaries of the operat‐
	      ing system or its bootstrap loader.

	      Selected	by mk(1) when $objtype is 386, this file configures mk
	      to compile for the Intel x86 architecture.

       /rc    Isomorphic to the architecture-dependent directories, this holds
	      executables and libraries for the shell, rc(1).

	      Directory of shell executable files.

	      Directory of shell libraries.

	      Startup code for rc(1).

       /lib   Collections of data, generally not parts of programs.



       etc.   Databases.

	      The network database used by the networking software; see ndb(6)
	      and ndb(8).

	      The file used by newns (see auth(2)) to  establish  the  default
	      name space; see namespace(6).

	      Bitmap font files.

	      Vector font files.

	      Directory	 of  Internet  `Requests  For  Comments', ranging from
	      trivia to specifications.

	      Maintains RFC collection; usually run from cron (see auth(8)).

       /sys   System software.

	      Directory of machine-independent C include files.

	      Pieces of programs not easily held in the various bins.

	      Directory of acid(1) load modules.

	      Software	used  to  assemble  the	 distribution's	  installation

	      Directory of troff(1) font tables and macros.

	      The yacc(1) parser.

	      The manual.

	      Other system documentation.

	      Log files created by various system services.

	      Top-level directory of system sources.

	      Source to the commands in the bin directories.

	      Source to the operating system for terminals and CPU servers.

	      Source to the operating system for file servers.

	      Source to the libraries.

       /usr   A directory containing home directories of users.

       /mail  Directory of electronic mail; see mail(1).

	      Directory of users' mail box files.

	      Directory of alias files, etc.

       /acme  Directory of tools for acme(1).

       /cron  Directory of files for cron(8).

	      System-specific files, often addenda to their namesakes, notably
	      cpurc, termrc, namespace, and consoledb.

       The following files and directories are modified in the	standard  name
       space, as defined by /lib/namespace (see namespace(6)).

       /      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 direc‐
	      tory containing the  appropriate	executables  for  the  current

       /dev   Mounted here is a union directory containing I/O devices such as
	      the console (cons(3)),  the  interface  to  the  raster  display
	      (draw(3)), etc.  The window system, rio(1), prefixes this direc‐
	      tory 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.

	      The  communications point for the connection server, ndb/cs (see

	      The communications point for the	Domain	Name  Server,  ndb/dns
	      (see ndb(8)).


	      Directories holding the IP protocol devices (see ip(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 con‐
	      nections to file servers.

	      The communication channel	 to  the  main	file  server  for  the

	      Mount point for factotum(4).

	      Mount point for the window system.

	      Mount  point  for	 the  terminal's name space as seen by the CPU
	      server after a cpu(1) command.

	      A place where machine kremvax's name space may be mounted.

       /tmp   Mounted here is each user's private tmp, $home/tmp.
