With 10 seonds you will not be very happy...
I think, you are searching for
----[ '/etc/defaults/rcS' ]---------------------------------------------
#
# /etc/default/rcS
#
# Default settings for the scripts in /etc/rcS.d/
#
# For information about these variables see the rcS(5) manual page.
#
# This file belongs to the "initscripts" package.
TMPTIME=0
SULOGIN=no
DELAYLOGIN=no
UTC=no
VERBOSE=no
FSCKFIX=no
RAMRUN=no
RAMLOCK=no
------------------------------------------------------------------------
and set TMPTIME to 1 which mean ONE DAY, but this will only work on
bootup...
and maybe you can use a cronjob executed each minute and the codesniplet
