Yeah, I agree too. It's not that cool but it's ok ...

| $ ls /etc/rc*.d/*ppp 
| /etc/rc0.d/K86ppp  /etc/rc2.d/S14ppp  /etc/rc4.d/S14ppp  /etc/rc6.d/K86ppp
| /etc/rc1.d/K86ppp  /etc/rc3.d/S14ppp  /etc/rc5.d/S14ppp
|
| $ sudo rename 's#\/etc\/rc(.)\.d\/(K|S)(.*)#\/etc\/rc$1\.d/_$2$3#' /etc/rc*.d/*ppp
| 
| $ ls /etc/rc*.d/*ppp 
| /etc/rc0.d/_K86ppp  /etc/rc2.d/_S14ppp  /etc/rc4.d/_S14ppp /etc/rc6.d/_K86ppp
| /etc/rc1.d/_K86ppp  /etc/rc3.d/_S14ppp  /etc/rc5.d/_S14ppp

and back again

| $ sudo rename 's#\/etc\/rc(.)\.d\/_(K|S)(.*)#\/etc\/rc$1\.d/$2$3#' /etc/rc*.d/*ppp
| 
| $ ls /etc/rc*.d/*ppp
| /etc/rc0.d/K86ppp  /etc/rc2.d/S14ppp  /etc/rc4.d/S14ppp  /etc/rc6.d/K86ppp
| /etc/rc1.d/K86ppp  /etc/rc3.d/S14ppp  /etc/rc5.d/S14ppp

Hmm, just doing a "chmod -x /etc/init.d/ppp" IS easier ;-)

Yes! And ist quite easy to implement ...

| if [ -f /etc/default/$SERVICE ]; then
| 	. /etc/default/$SERVICE
| fi
|
| if [ ! $START_SERVICE = 'YES' ]; then
|	log_warning_msg "Don't starting $SERVICE it's disables in /etc/default/$SERVICE"
|	exit 0
| fi
