Debian Question - How to start a programm with rcS the task having root privileges

[Michael Wuest <mwuest@gev5.gotdns.org>]

Hi there,

I did a small programm with gambas. It is there to control an LCD
panel for setting up display parameters of X11 and networking
parameters of my debian sarge distribution.

everything is fine, but the program needs root privileges to
access the LCD panel (via /dev/lcd), the networking file
"interfaces", the ifup/ifdown/ifconfig commands and so on.

Now my question is, what do I have to do to get the programm
started at boot up (with rcS???) having root privileges???

Thanks, best regards,
Michael.
