It's pretty straight forward. The man page will tell you all about
it. 

To create the default setup, do a:

$ update-rc.d apache2 defaults 

Where update-rc.d differs from chkconfig however is due to it being,
as you say, for package scripts. If links already exist, it won't
overwrite them. So, it's really only for creating the links
initially. This is a Debian policy thing. The assumption is that, if
the links exist, the sys admin did it and the package scripts should
respect that.

If you want to change the links, you need to remove them first. Issue a:

$ update-rc.d -f apache2 remove

The -f is needed if /etc/init.d/apache2 stills exists, which I assume
it does otherwise we wouldn't be having this conversation.

Then you can do as the above. Remember, this is only if you want to
change the existing set of links. If all you want to do is create them
initially, you don't need to do the remove.

Cheers,
Paul.
