NAME    [Toc]    [Back]

       it - configure a system after installation

SYNOPSIS    [Toc]    [Back]


DESCRIPTION    [Toc]    [Back]

       The  it  program executes scripts before transferring control
 of the system to the user, typically before the first
       user  logs in.  The it program executes programs that collect
 information such as system name, passwords, timezone,
       and current date.

       A system can be in a run level at any given time; each run
       level has a specific group of processes that run  at  that
       level.  The  init program operates in one of four run levels:
 0, s, 2, or 3. The run level  changes  when  init  is
       invoked  by a privileged user.  The it program is run from
       /etc/inittab whenever the system is booted or rebooted, or
       when a level transition occurs for some other reason, such
       as within init3. The it program first determines which run
       level  the  system  is  coming  up under. Next it turns on
       shared libraries  and  swap  and  then  searches  for  any
       /sbin/it.d/run-level  directories, where run-level names a
       system run level; for example,  2.d,  3.d,  23.d,  and  so
       forth.   If  any  such  directories exist, it collects the
       names of all files in those directories.  These files  are
       typically  links  to files in the /sbin/it.d/bin directory
       and are created beforehand by itruns(8). After  collecting
       the file names, it sorts them, eliminates duplicate references,
 orders the names as  specified  by  the  data  file
       /sbin/it.d/data/options.mask,   executes  the  files,  and
       finally removes the files  it  executed.   After  all  the
       files  collected  from the run level directories have been
       handled, it exits.

       The /sbin/it.d/data/options.mask file  contains  a  single
       line  with  a list of file names separated by colons.  The
       it command executes collected files in the order in  which
       they  appear  from left to right in the options.mask file.
       Programs not listed in the options.mask file are  executed
       after  those  defined in options.mask. These "unspecified"
       programs are run in the order into which  they  were  initially
  sorted; that order is controlled by the LC_COLLATE
       environmental  variable  and  the  specifications  in  the
       /usr/lib/nls/loc/locale files.
