Hi, just talking into the wild here.

The policyrcd-script-zg2 package shows how this could be addressed. My script just looks into /usr/local/sbin/policy-rc.d or /etc/policy-rc.d and executes the files if they exist. This just moves the place where the local admin places his local script into a directory which is in her local domain, a rather trivial task. For the task at hand, I would think that it would probably be a good idea to have /etc/policy-rc.d as a directory which holds files called like services. For example, to stop apache from being started on package installation and upgrades, one would drop a file into /etc/policy-rc.d/apache. That file could either contain configuration data like a single line of "allowed", "undefined", "unknown", "forbidden", "error" (see other values in /usr/share/doc/sysv-rc/README.policy-rc.d.gz) or have there a simple shellscript with the appropriate exit code. That way would allow a per-service configuration of process start behavior. The script handling the /etc/policy-rc.d/* file/scripts could even be in a package (and I could finally retire the rather trivial policyrcd-script-zg2). Disclaimer: I do not know whether the new nice systemd world still honors invoke-rc.d mechanisms. The scripts and documentation originate from sysv-rc which is at least still present on my systemd-pid1-sid systems, so there is hope.
