       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 ex‐

       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  ac‐
              cording  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.

              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.

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

              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  ar‐

       /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 en‐
              vironment variables such as $cputype.

       /net   Mounted here is a union directory formed of all the network  de‐
              vices 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 de‐
              bugging 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  ma‐

              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.
