NAMESPACE(4) NAMESPACE(4) NAME namespace - structure of conventional Inferno name space SYNOPSIS none DESCRIPTION The list below gives an overview of the Inferno distribution file tree, organised into related categories. / The root directory. To programs running outside Inferno, this corresponds to the directory in which Inferno has been installed (e.g. C:\inferno under Windows). Mount points The following are all placeholders for filesystems that are mounted when Inferno is running. They contain no data files. Although an Inferno namespace is a dynamic entity, and devices can be mounted anywhere therein, many programs assume that devices have been mounted in the standard places, as suggested by the skeleton directories listed below. /dev The standard mount point for devices (e.g. cons(3)) /env The standard mount point for the env(3) device. /mnt A directory containing mount points for applica- tions. /chan An empty directory, used for holding files cre- ated with sys-file2chan(2). /net The standard mount point directory for network interfaces. /n A directory containing mount points for file trees on local devices or imported from remote systems. /prog An empty directory, the mount point for the prog(3) device. /nvfs An empty directory, the mount point for a non- volatile RAM filesystem on devices that have one. /tmp Mount point for private directory of temporary files (eg, /usr/user/tmp). /mail Conventional place to mount mailboxes. Limbo applications /dis Dis executables (commands) /dis/lib Dis libraries /dis/wm Dis commands that run under wm(1). /man Manual pages. /doc Documentation other than manual pages. Page 1 Plan 9 (printed 11/17/24) NAMESPACE(4) NAMESPACE(4) /appl Source to Limbo applications. /appl/cmd Source to the commands in /dis (as documented in Section 1). /appl/wm Source to the commands in /dis/wm /appl/lib Source to the modules in /dis/lib (as documented in Section 2). /module Limbo module declarations Supporting data /acme Programs and guide files specific to acme(1). /fonts Font definitions /locale Timezone and locale information /icons Contains image(6) files used by programs. /icons/tk Default directory searched by tk's -bitmap option (see options(9)). /lib Static program-specific data. /lib/ndb Network configuration files used by cs(8), dns(8) and others. Administration /keydb Storage of secrets and certificates on signers (authentication servers). /services A jungle of program-specific configuration files. Platform specific /Platform Binaries specific to Platform. Current platforms include Inferno (native binaries), FreeBSD, Hp, Irix, Linux, Nt, Plan9, Solaris and Unixware. /Platform/arch/bin /Platform/arch/lib /Platform/arch/include Platform specific binaries, libraries and include files respectively. Arch is the architecture type, as defined in 2c(10.1) and held in the $objtype environment variable. /usr A directory containing user directories. Inferno source code /emu Directory containing source specific to emu(1). /emu/port Cross-platform source for emu(1). /emu/Platform Platform-specific source for emu(1). /libkfs The emu version of kfs(3). /libbio /libregexp Source to libraries used by hosted commands. /lib9 Source to the Plan 9 emulation library, used by emu and the hosted commands. /libmemdraw /libmemlayer /libprefab /libkern Page 2 Plan 9 (printed 11/17/24) NAMESPACE(4) NAMESPACE(4) /libkeyring /libdraw /libinterp /libtk Inferno source used by both native and hosted versions of Inferno. /asm /limbo Source to the two hosted Inferno commands of the same name. /utils Source to hosted utilities run from emu(1) via the cmd(3) interface. /tools A directory containing source directories for hosted tools used in building Inferno (e.g. mk(10.1)). /os A directory holding source directories for the native versions of Inferno. /os/init Limbo source for platform-specific initiali- sation procedures. /os/port Portable native kernel source. /os/arch Arch-specific native kernel source. /os/kfs The native kernel version of kfs(3). Minimal name space The above is all very well on a system with lots of storage, but what is actually necessary for the running of Inferno? The following gives a quick summary of the structure that must be provided for Inferno to function correctly. /dis This must contain Dis modules for all the appli- cations you plan to run, and the modules they depend on. Disdep(1) can be useful when trying to determine this set. /dev /env /chan /net /prog /tmp All empty unwritable directories, place holders for mounted services and applications. Often these are provided by the built-in root(3). /mnt A directory containing mount points for applica- tions. /n A directory containing mount points for remote file systems. Files needed to run as a server /keydb/keys See keyfs(4), logind(8) and signer(8). /keydb/signerkey See createsignerkey(8) and logind(8). Files needed to run the window manager /fonts At least one font must be provided - a default Page 3 Plan 9 (printed 11/17/24) NAMESPACE(4) NAMESPACE(4) font for Tk to use. /icons/tk This should contain icons used by applications that run within Tk. /user/user At least one user directory must exist if logon(1) is to function correctly.
