Yes, that is what I am suggesting. And if the upgrade overwrites your
changes, you should file a bug report and ask the maintainer to come
into compliance with Debian Policy:

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. [1]


Configuration file handling must conform to the following behavior:
- local changes must be preserved during a package upgrade, and
- configuration files must be preserved when the package is removed,
and only deleted when the package is purged. [2]
