rcS(5)                            Debian Administrator's Manual                            rcS(5)

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 /run/nologin
              is created during the boot process and deleted at the end of it.  The login(1) pro‐
              gram refuses to allow non-root logins so long as /run/nologin exists.  If  you  set
              the variable to no then it is advisable to ensure that /run/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  com‐
              mands  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, RAMRUN and UTC variables are no longer used.  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.
