I believe that the "initscripts" package (which you almost certainly
have got installed already) handles this already - if you cast your
eyes over /etc/init.d/urandom you should see similar code.

For wheezy, the normal place for startup/shutdown is in /etc/init.d/ -
symlinks will be created from /etc/rcX.d/ as appropriate for each
runlevel (X is a run level in this context).
For simple hacks by the system admin, tweaking /etc/rc.local is also
acceptable - packages are not allowed to interfere with that.
There is a plethora of information available about this -
may be a good starting point.
 Let's not get into the whole systemd saga here....
Hope this helps
