Where are the ln examples?
For both the soft link and the hard link the examples of how to actually use ln to create the links appear to be missing.

In Ubuntu's community, however:

To deactivate a script (meaning that it will not be executed at bootup), remove the corresponding symlink from /etc/rc?.d. Do not use the update-rc.d command for this purpose! It is only used in package installation scripts, and not designed for this kind of runlevel management.

However, there is a problem:
* To restore the links with the right S?? or K?? values you have to look up those values on another system or take a look at the deb-Package install scripts …

Agree with Dmitriy. But I only investigated the man after reading this post. Was going to post the very same quote about it, that Dmitriy already posted

Following Dmitriy's comment, that's precisely what the -disable- option does in the update-rc.d command(renames the service's symbolic links from S to K) , and to re-enable the service…well just use the -enable- option in the update-rc.d command =-)
Cheers!

Given Dmitriy's comment it sounds another approach would be to use:

# update-rc.d proftpd disable

This should prevent the upgrade scripts from putting the symlinks back.

A common system administration error is to delete the links with the thought that this will "disable" the service,
i.e., that this will prevent the service from being started. However, if all links have been deleted then the next
time the package is upgraded, the package’s postinst script will run update-rc.d again and this will reinstall
links at their factory default locations. The correct way to disable services is to configure the service as
stopped in all runlevels in which it is started by default. In the System V init system this means renaming the
service’s symbolic links from S to K.

man update-rc.d
