Is there an equivalent to /etc/rc.d/rc.local in ubuntu?

On my FC2 system /etc/rc.d/rc.local says:

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

There are sometimes some local issues that an old dos user like me first
looks at an old note of equivalents for autoexec.bat...
My note points to rc.local as the least dangerous place for a less than
expert like me to mess with the init scripts... I mean I doubt that it
would be a good idea for me to just add symlinks to /root/bin/ scripts
in /etc/rcS.d???
