NAME

       rcS - variables that affect the behavior of boot scripts

DESCRIPTION

       The /etc/default/rcS file contains variable settings in POSIX format:

	    VAR=VAL

       Only one assignment is allowed per line.  Comments (starting with '#') are also allowed.

OPTIONS

       The following variables can be set.

       TMPTIME
	      On boot the files in /tmp will be deleted if their modification time, file status time and access time are all at least TMPTIME days
	      ago.  A value of 0 means that files are removed regardless of age.  If you don't want the system to clean /tmp then set TMPTIME to a
	      negative value (e.g., -1) or to the word infinite.

       SULOGIN
	      Setting  this  to  yes causes init to spawn a sulogin on the console early in the boot process.  If the administrator does not login
	      then the sulogin session will time out after 30 seconds and the boot process will continue.

       DELAYLOGIN
	      Normally the system will not let non-root users log in until the boot process is complete and the system has finished  switching	to
	      the  default  runlevel  (usually	level  2).   However,  in  theory it is safe to log in a bit earlier, namely, as soon as inetd has
	      started.	Setting the variable to no allows earlier login; setting the variable to yes prevents it.

	      Some details: The DELAYLOGIN variable controls whether or not the file  /var/lib/initscripts/nologin  is	created  during  the  boot
	      process  and  deleted  at  the end of it.  /etc/nologin is normally a symbolic link to the latter location, and the login(1) program
	      refuses to allow non-root logins so long as (the target of) /etc/nologin exists.	If you set the variable to no then it is advisable
	      to ensure that /var/lib/initscripts/nologin does not exist.

       VERBOSE
	      Setting  this  option to no (in lower case) will make the boot process a bit less verbose.  Setting this option to yes will make the
	      boot process a bit more verbose.

       FSCKFIX
	      When the root and all other file systems are checked, fsck is invoked with the -a option which means  "autorepair".   If	there  are
	      major  inconsistencies  then the fsck process will bail out.  The system will print a message asking the administrator to repair the
	      file system manually and will present a root shell prompt (actually a sulogin prompt) on the console.  Setting this  option  to  yes
	      causes  the fsck commands to be run with the -y option instead of the -a option.	This will tell fsck always to repair the file sys-
	      tems without asking for permission.

       ASYNCMOUNTNFS
	      Set this to 'no' to disable asynchronous mounting of network drives when the network interfaces are mounted, and instead do it  only
	      once  when  the  machine	boots.	The default is 'yes'.  It is useful to disable this on machines where the root file system is NFS,
	      until ifup from ifupdown works properly in such setup.

NOTE

       The EDITMOTD, RAMRUN and UTC variables are no longer used.  The RAMLOCK, RAMSHM and RAMTMP variables have been moved to /etc/default/tmpfs;
       RAMSHM  and  RAMTMP  settings  in  rcS  are  used  (if  set)  for  backward  compatibility,  but  will be overridden by settings enabled in
       /etc/default/tmpfs.  See tmpfs(5) for further details.  The settings are not automatically migrated to /etc/default/tmpfs.   Please  update
       /etc/default/tmpfs  appropriately.   The UTC setting is replaced by the UTC or LOCAL setting in /etc/adjtime, and should have been migrated
       automatically.  See hwclock(5) and hwclock(8) for further details on configuring the system clock.
