I've seen some complicated examples on this thread, and want to suggest
a simple one:

1. create a regular shell script in /etc/rc.d, name it whatever you like
(for example: "/etc/rc.d/myscript")
2. chmod a+x the script
3. you're done.

This will work for the recent versions of FreeBSD (you didn't say for
which version do you need it).

A more semantically pure example (and the one that's preferred if your
script starts an external application - a web server or something like
that) is to put the script in /usr/local/etc/rc.d. In any case, the
syntax and everything else is the same.

An advanced feature is to regulate when the script will be executed (in
Linux, this is accomplished by all those ugly symlinks like
S86Something). Here it is done by adding special comments to the
beginning of the file in the format

# AFTER: FILESYSTEMS

or

# BEFORE: LOGIN

See rcorder(8) man page for details.

(most of the advices given here will also work on NetBSD).
