       rcS - variables that affect the behavior of boot scripts


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


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


       The following variables can be set.

              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.

              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.

              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

              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.

              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.


       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.
