I am afraid this is not the case. In the first instance, the "startup"
on a NetBSD system, as it comes from the base installation is split up
into more than one section, and in fact, can be split-up infinitely if
one wishes to so do, i.e.:
[ $? -ne 0 ] && . /etc/rc.single
... < things following remount ommitted >
if [ ! -f /etc/multi-user-mode ]; then
[ ! -f /etc/no-net ] && . /etc/rc.local
"Started Network Daemons......"
[ ! -f /etc/no-daemons ] && . /etc/rc.news
With an /etc/rc like the above, the following line would take the system
down, and restart all system tasks save for INN startup, and anything
else on INN's rc script.
echo "" > /etc/no-daemons ; kill 1
What is instead being proposed, is changes to the program /sbin/init
which is one of the lowest levels of the UNIX operating system, and which
runs continually from power-on and boot-up.

All of the above are possible with the current setup however, as is
shown in my example. Installation and de-installation of programs has
little to do with /etc/rc.* unless the program needs to be installed in
the system startup, which applies only to daemon processes.

I am perfectly able to edit my own rc, however, these are not just
changes to the rc files, they are the addition of a new system of
understanding them to the program init.
