Hi Malte,
That's great news!
Last year I was working with Kenneth, trying to "dockerize" OACS in a Debian 9 container. However, we had to park the project unfortunatelly.
In my research, I found ]PO['s documentation and basics sources, based on Centos.
MALTE: "Contrary to Frank our goal is to provide ]project-open[ packages similar to .LRN as an addon to OpenACS as this will help decrease technical debt (in our eyes)."
MALTE: "work through the tedious updates necessary to get it running based off OpenACS 5.10 & PG11"
I have expertise in that "tedious" task. :)
In the past, I've created scripts to install PO from scratch (using APM package) in an OACS core installation :)
Let me know if you need help and how to jump in.
MALTE: "And please feel free to fork the github repository so we can merge your ideas an improvements into it."
Doing now! ... :)
Best wishes,
I
