NAME    [Toc]    [Back]

     rc2 - run commands	required for multi-user	environment

SYNOPSIS    [Toc]    [Back]

     /etc/rc2

DESCRIPTION    [Toc]    [Back]

     /etc/rc2 is executed via an entry in /etc/inittab and is responsible for
     the initializations that bring the	system to a ready-to-use state,
     traditionally state 2, which is called the	"multi-user" state.

     /etc/rc2 runs files beginning with	S in /etc/rc2.d.  These	files are
     executed by /bin/sh in ascii sort-sequence	order (see FILES below for
     more information).

     Each of these files may also check	the state of the corresponding
     chkconfig flag for	that function.	If the state is	on, the	script starts
     that function; if the state is off, it does not start that	function.
     (See chkconfig(1M)).

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

	  Setting and exporting	the TIMEZONE variable.

	  Setting-up and mounting the user (/usr) and other filesystem(s).

	  Cleaning up (remaking) the /tmp directory.

	  Initializing the network interfaces, mounting	network	filesystems,
	  and starting the appropriate daemon processes.

	  Starting the cron daemon by executing	/etc/cron.

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

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

EXAMPLES    [Toc]    [Back]

     The following are simplified examples of the files	found in /etc/rc2.d.
     The filenames are prefixed	by an S	and a number indicating	the execution
     order of the files.

     filesystems
	  # set	up and mount filesystems
	  cd /
	  fsck -m -c -y
	  /etc/mount -at efs

     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 /var/spool/locks/*

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

     See rc0(1M) for the system	shutdown procedure.

FILES    [Toc]    [Back]

     Files in /etc/rc2.d must begin with an S or a K followed by a number and
     the rest of the filename.	Upon entering run level	2, files beginning
     with S are	executed with an argument of start ; if	entering run level 2
     from some state other than	single-user mode (ie: from other than run
     level 1 or	s), files beginning with K, are	first executed with an
     argument of stop.	Files in /etc/rc2.d are	typically symbolic links to
     files in /etc/init.d.  Files beginning with other characters are ignored.
