Having given rcS a more thorough look today and compared with rc, I
noticed a little other thing.

rc uses:
for i in /etc/rc$runlevel.d/S*
do
	[ ! -f $i ] && continue
 	if [ $previous != N ]
then
	<the rest here>

The [0-9][0-9][0-9] are only used to construct the 
sysinit_start, previous_start and previous_stop variables. The actual
running of the script is just $i stop or $i start that's constructed
from a "for in S*" or "for in in K*" and it lets bash sort the scripts
in numeric order.

So, the change to rcS was not from S?? to S[0-9][0-9][0-9], but should
have been from S?? to S*

Nice, eh? As i'm redoing the network scripts I'll have a closer look at
our master scripts (rc and rcS). It seems that there's quite a bit of
stuff in there that can be changed, made easier, etc.

Sorry for the confusion, I'll reopen the bug, update book and close it,
so this change will be logged there.

I hope I'm doing the right thing by changing it to S*. 

Let's run a test. The old way:
gerard:/etc/rcS.d$ for i in S??*; do echo $i; done
S100localnet
S200checkfs
S300mountfs
S400hdparm

The new way:
gerard:/etc/rcS.d$ for i in S*; do echo $i; done
S100localnet
S200checkfs
S300mountfs
S400hdparm

There's no checking if the S (or K's) is preceded by three numbers, but there's
no real check in rc either. It'll be fixed up soon.
