rcS -- defaults used at boot time
/etc/default/rcS contains information in the following format:
Only one value per line is allowed. Comments are allowed too and must
start with the ‘‘#’’ character.
The following options can be set, the defaults values are shown:
On bootup the files in /tmp will be cleaned up if their
modification time was more than TMPTIME days ago. A value of
zero means that all files are removed regardless of age. If you
don’t want the system to clean /tmp set TMPTIME to a negative
value (-1) or the word infinite.
Setting this to yes causes init to spawn a sulogin on the
console as one of the first things in the boot process. If the
administrator does not login, the sulogin will timeout after 30
seconds and the boot process will continue.
Normally the system will not let anyone login until the boot
process is complete and and the system has come up completely in
the default runlevel (usually level 2). However theoretically
it’s possible to login a bit earlier, as soon as /usr/sbin/inetd
is started. The default value of no prevents this, setting it to
yes allows it.
UTC= This is used to interpret the system (BIOS) clock. If this
option is set to no the system clock is supposed to be set at
local time. If this option is set to yes the system clock is
supposed to be set at UTC (Universal Time, a.k.a. GMT).
Setting this option to no will make the bootup a bit less
At boot time the system edits the first line of the file
/etc/motd and replaces it with the output from the command uname
-a. Setting this to no prohibits that.
When the root and all other filesystems are checked, this
happens with the -a flag which means autorepair. If there are
really big inconsistencies, the fsck will bail out. The system
will print a message asking the administrator to repair the
filesystem maually and 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 always repair the filesystems without
any interaction but might irreversibly damage your file
