RC2(1M-SysV)        RISC/os Reference Manual         RC2(1M-SysV)



NAME
     rc2 - run commands performed for multi-user environment

SYNOPSIS
     /etc/rc2

DESCRIPTION
     This file is executed via an entry in /etc/inittab and is
     responsible for those initializations that bring the system
     to a ready-to-use state, traditionally state 2, called the
     "multi-user" state.

     The actions performed by /etc/rc2 are found in files in the
     directory /etc/rc.d and files beginning with S in
     /etc/rc2.d.  These files are executed by /bin/sh in ascii
     sort-sequence order (see FILES for more information).  When
     functions are added that need to be initialized when the
     system goes multi-user, an appropriate file should be added
     in /etc/rc2.d.

     The functions done by /etc/rc2 command and associated
     /etc/rc2.d files include:

          Setting and exporting the TIMEZONE variable.

          Setting-up and mounting the user (/usr) file system.

          Cleaning up (remaking) the /tmp and /usr/tmp direc-
          tories.

          Loading the network interface and ports cards with pro-
          gram data and starting the associated processes.

          Starting the cron daemon by executing /etc/cron.

          Cleaning up (deleting) uucp locks status, and temporary
          files in the /usr/spool/uucp directory.

     Other functions can be added, as required, to support the
     addition of hardware and software features.

EXAMPLES
     The following are prototypical files found in /etc/rc2.d.
     These files are prefixed by an S and a number indicating the
     execution order of the files.

     MOUNTFILESYS
          #    Set up and mount file systems

          cd /
          /etc/mountall /etc/fstab

     RMTMPFILES
          #  clean up /tmp
          rm -rf /tmp
          mkdir /tmp
          chmod 777 /tmp
          chgrp sys /tmp
          chown sys /tmp

     uucp
          #    clean-up uucp locks, status, and temporary files

          rm -rf /usr/spool/locks/*

     The file /etc/TIMEZONE is included early in /etc/rc2, thus
     establishing the default time zone for all commands that
     follow.

FILES
     Here are some hints about files in /etc/rc.d:

     The order in which files are executed is important.  Since
     they are executed in ascii sort-sequence order, using the
     first character of the file name as a sequence indicator
     will help keep the proper order.  Thus, files starting with
     the following characters would be:

          [0-9].    very early
          [A-Z].    early
          [a-n].    later
          [o-z].    last


     Files in /etc/rc.d that begin with a dot (.)  will not be
     executed.  This feature can be used to hide files that are
     not to be executed for the time being without removing them.
     The command can be used only by the super-user.

     Files in /etc/rc2.d must begin with an S or a K followed by
     a number and the rest of the file name.  Upon entering run
     level 2, files beginning with S are executed with the start
     option; files beginning with K, are executed with the stop
     option.  Files beginning with other characters are ignored.
