Interesting information about how the system starts and kills the various
scripts.

But it doesn't say how to add a script to rc2.d for example. Does one just
arbitrarily pick a number to go before a copy of the script?

I can understand starting at level S and then moving to Level 1 and then
Level 2 for a server, but what triggers the system to move to level 3,4, & 5
... level 6 is shutdown right?
