Comment 2 for bug 1819721

This change has the potential to be a showstopper in some cases.

We're managing Tomcat on a lot of servers using Puppet. Puppet currently installs slightly modified /etc/init.d/tomcat8 and /etc/default/tomcat8 files. The changed init.d file adds support for e.g. reading a /etc/default/tomcat8.local file if it exists (in addition to /etc/default/tomcat8), making it possible to make temporary and/or local changes to certain environment variables used during Tomcat startup without having to add that change to Puppet as well. After updating to Tomcat 8.5.39-1ubuntu1~18.04 currently in proposed, this override no longer works, I guess because /etc/init.d/tomcat8 isn't used at all any more.

Making these kind of intrusive changes one year after an LTS release clearly damages the trust users have in Ubuntu LTS releases being stable across its lifetime.
