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.

       UTC    This  is  used to govern how the hardware real time clock is interpreted when it is
              read (e.g., at boot time, for the purpose of setting the system clock) and when  it
              is  written (e.g., at shutdown).  If this option is set to no then the system clock
              is assumed to be set to local time.  If the option is set to yes  then  the  system
              clock  is  assumed  to be set to something approximating Coordinated Universal Time
              (UTC).  (POSIX systems keep a variant of UTC, without leap seconds.)

              On  contemporary  Debian  systems  (although   change   has   been   requested   at
              http://bugs.debian.org/346342),  if  UTC is set to no then /usr/share/zoneinfo must
              be readable early in the boot process.  If you want to  keep  /usr  on  a  separate
              filesystem  then  you must still ensure that the target of /etc/localtime points to
              the correct zone information file for the time  zone  of  the  time  kept  in  your
              hardware real time clock.

       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 systems without asking for permission.

NOTE

       The EDITMOTD and RAMRUN variables are no longer used.
