Debian doesn't pay much attention to run levels. Normal use of a Debian
system involves only run level 2 for both console-only and Xwindows.
Run levels have been left available to local use. So, why do you need
to change symlinks of all run levels on a Debian system? You shouldn't
need to unless you have done something that is quite outside the Debian

In a standard Debian system, there is only the run level 2 symlink needing
update when you want to enable/disable a deamon. When this is needed as
part of some fix of a problem, the advice on debian-user is usually to
just edit the symlink. E.g. make it a real file that is empty. When you
want to use the deamon, use the command 
/etc/init.d/<deamon> start

When you tire of it, use
/etc/init.d/<daemon> stop

(as root of course)

I think your file will not be overwritten by subsequent upgrades of the
package that installed the original. 

When (if) you want to start using the deamon as intended by the
packager, recreate the symlink in run level 2. 

But maybe I misunderstand what you want to accomplish.
