Why don't you want to use sudo? Here's what I do in one of my backup
scripts that need to run setuid:
if [ `id -u` != 0 ] ; then
if [ $TRYINGSUDO = 1 ] ; then
echo "Cannot get admin priviledges! All files may not get backed up"
else
TRYINGSUDO=1
export TRYINGSUDO
exec sudo $0 "$@"
fi
fi
I have sudo configured to not prompt for a password. When a regular
user executes the script, it immediately re-executes itself via sudo.
The user doesn't need to know about sudo at all.
