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) program 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  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, 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.
