The last script run on startup is rc.local, the last script run before
rc.local is in the rc?.d where ? is the runlevel that you stop at. For
instance with a default startup to X, it is rc5.d. And the last script
run in that dir, is the one with the largest number after the S. Note
that all these scripts are links to one set kept in init.d, so as to
eliminate duplication of scripts in each runlevel.
The last script run on shutdown is thus in rc6.d, the shutdown dir. and
it is the one with the largest number again.
Note that the scripts in init.d are intended to be run with either
start, stop, restart or status as command line options. In each rc?.d
dir if the file is linked beginning with an S, then start is passed
as the argument, if the link begins with K stop is passed as an argument
which is why all the files in rc6.d are prepended with a K, and nearly all
the others are S
Though all you probably want to do is add a call to the script you want
to run at the bottom of /etc/rc.d/rc.local. Note that if the script is
going to block, i.e. not become a daemon automatically or finish quickly
then the whole system will stop on startup waiting for it to finish, so
put an & after the command. That used to be a big problem with sendmail
when the network would go down as it wouldnt daemonize until it had
found a network, terrible nuisance.
The top of /etc/inittab tells you which runlevel is intended for what.
