hier − file system hierarchy

DESCRIPTION

The following outline gives a quick tour through a representative DOMAIN System directory hierarchy.  Note that we start at the node (rather than the network) root. 

Most installations take advantage of DOMAIN/IX’s variant links to support both a sys5 and a bsd4.2 filesystem.  These variant links are generally limited to the directories etc, /bin, and /usr, as noted below. 

/ (slash) The root directory of the local disk. 

/bsd4.2
Root of bsd4.2 filesystem. 

/sys5 Root of sys5 filesystem. 

/dev/ Device files documented in section 4 of the DOMAIN/IX Programmer’s Reference Manual).  sio? serial I/O ports ptyp?, ttyp? pty’s, see crpty(8) rmt? magtape descriptors rct? cartridge tape descriptors

/tmp/ Temporary files, usually a link to `node_data/tmp

/sys/ DOMAIN System programs and information.  boot system boot program node_data/ per-node information   etc.rc per-node boot-time script   tmp temporary files, link to /tmp   usertmp temporary files, link to /usr/tmp   startup.* DM startup command script   .    .    .  dm/ the Display Manager and screen fonts   dm  Display Manager program   fonts  screen fonts   *keys* key definitions files   input DM input pad   output DM output pad   .    .    .  mbx interprocess communications mailboxes types file type information for streams managers traits/ trait information for streams managers   .    .    .  tcp/ the tcp server and associated files spm/ the server process manager and associated files print print server files and data  queue print queue

/bin/ Utility programs documented in the DOMAIN/IX Command Reference Manual.  (See also /usr/bin/.)  On most nodes, /bin is the variant link $(SYSTYPE)/bin, which resolves to either /bsd4.2/bin or /sys5/bin, based on the current value of the SYSTYPE environment variable.  cc C compiler csh C Shell ed line editor sed stream editor .  .  . 

/etc/ System files, essential data, maintenance and administration utilities.  On most nodes, /etc is the variant link $(SYSTYPE)/etc, which resolves to either /bsd4.2/etc or /sys5/etc, based on the current value of the SYSTYPE environment variable.  rc boot time shell script (link to  `node_data/etc.rc) r*d Internet server daemon programs.  passwd The “password” file, crpasswd program to create passwd  from network registry information.  cron the clock daemon,

/usr/ A general-purpose directory.  On most nodes, /usr is the variant link $(SYSTYPE)/usr, which resolves to either /bsd4.2/usr or /sys5/usr, based on the current value of the SYSTYPE environment variable.  bin/ additional commands ucb/ additional commands dict/ word lists include/ standard C #INCLUDE files spellhist history file for spell(1) lib/ object libraries   atrun scheduler for at(1)   lint/ utility files for lint   tmac/ macros for troff(1)   font font width tables for troff(1)   uucp/ programs and data for uucp(1C) man/ reference manual entries   man?/ unformatted manual pages for chapter ?    cat?/ formatted manual pages for chapter ?  spool/ delayed execution files, normally a  link to a directory on a centrally  administered node.  uucp/ work files and staging area for uucp(1C),  normally a link to a directory on a centrally  administered node.
