Make deployment-time migration work
Add classpath items, package recommendation and systemd read/write path to make deployment-time migration work. Please note that this is my first ever patch to Debian, so I might get things wrong.
- Classpath change: tested by manually changing the file in a live Tomcat. (I don’t know how to build this code on my own.)
- Package recommendation: not tested, but I assume not much can go wrong.
- systemd change: tested by manually changing the unit file back in July. In the meantime, I’ve done a clean install on my computer and don’t have Tomcat installed anymore. I hope I remember correctly what I did.
