Hi, did you manage to find out where the problem is? I use this code for testing: https://github.com/KnCMiner/spi-test

Not via armbian-config. This is just a very simply way to do an initial setup. Here is the code that basically happens behind the scenes: https://github.com/armbian/configng/blob/main/tools/modules/software/module_nextcloud.sh So nothing fancy. just a docker run command. I personally prefer using docker-compose.yml instead of endless docker commands. Stuff is well-arranged and after adjusting like mounts down, up and ready to go. As mentioned above for customized installation please refer to the origin of the nextcloud container linuxserver.io. I am pretty sure they have examples for docker compose as well.

Yes. I disabled the patch you mentioned (patch/kernel/archive/sunxi-6.12/series.conf#L472) and built a bookworm minimal edge image with this and successfully booted an Orange Pi Zero 2 H616. I cannot answer this. I am using my Orange Pi One Plus (H6) headless only. Maybe anyone else can.

It may be possible to change the mount parameters of an already installed docker container. Is it possible to add mount options?

By default we mount all containers (data and config) folders under /armbian which has rights of 1st normal user of the OS - most expected use case scenario. If you want more complex deployment, you need to create your own Docker run / compose and mount containers folder elsewhere or try to bind mount what you need - on the OS level. Armbian-config is designed for inexperienced Linux users that would likely use default setup scenario. We purpusefully don't allow too many config options which would be confusing or / and would require additional learning in the process of installation. If you want to do it more on your own, please check this article https://docs.linuxserver.io/images/docker-nextcloud/ This is the fundation behind armbian-config way.
