debian policy for init scripts

It could be useful to add your /etc/init.d/ script to debian/conffiles to avoid overwriting local changes.
Sometimes sysadmins change the init scripts and with this little tip you can help them in case of package upgrades.

From the Debian Policy Manual:
"The /etc/init.d scripts must be treated as configuration files, either (if they are present in the package, that is, in the .deb file) by marking them as conffiles, or, (if they do not exist in the .deb) by managing them correctly in the maintainer scripts (see Configuration files, Section 10.7). This is important since we want to give the local system administrator the chance to adapt the scripts to the local system, e.g., to disable a service without de-installing the package, or to specify some special command line options when starting a service, while making sure their changes aren't lost during the next package upgrade.
