George, why would Miquel be wrong about this? He and Bruce Perens are
the ones the wrote the boot scripts for Debian.
/etc/init.d/rcS is the FIRST thing that is run. It call runs the links
in /etc/rcS.d then calls rc.boot(for backwards compatibility) and then
/sbin/setup.sh. Then control is passed onto the appropriate run-level
scripts in rc[2-5].d. So the appropriate place for local setup scripts
is in /etc/init.d with links in the rc[2-5].d directores made by using
update-rc.d.

1. Boot.
When the systems boots, the /etc/init.d/rcS script is executed. It
in turn executes all the S* scripts in /etc/rcS.d in alphabetical
(and thus numerical) order. The first argument passed to the
executed scripts is "start". The runlevel at this point is "N" (none).
Only things that need to be run once to get the system in a consistent
state are to be run. The rcS.d directory is NOT ment to replace rc.local.
One should not start daemons in this runlevel unless absolutely
nessecary. Eg, NFS might need the portmapper, so it is OK to start it
early in the bootprocess. But this is not the time to start the
squid proxy server.
2. Going multiuser.
After the rcS.d scripts have been executed, init switches to the
default runlevel as specified in /etc/inittab, usually "2".
Init then executes the /etc/init.d/rc script which takes care of
starting the services in /etc/rc2.d.

then
/sbin/setup.sh
