But often, multiple processes are needed to shut down a daemon. As
this is a common task, then let's lump them together. If you need
more granularity, we're not taking away the individual commands. If
anything, we're exposing the necessary steps to users not yet familiar
with a particular package.
To put it another way: you've got touch, wall, and halt; do you still
use shutdown?

Fix /etc/initscr (or whatever it is that runs the scripts; I've
forgotten since then). Solaris honors #!, it's just got a broken init
system that is likely easily fixed.

You know as well as I do that most SVR4-worlders would find /etc/rc a
step backwards. That just plain ain't gonna happen.

We're not talking about adopting the entire SysV init heirarchy, which
is where most of the ratsnest comes from. We're talking about
augmenting the existing rc system with a little bit more.

Perhaps I should point out that the latter handles both startup and
shutdown. The former handles startup only.
Happy hacking,
