So I don't know about everyone else, but for myself I've had my helios64 running on Armbian 22.02 with the 5.15.93-rockchip64 kernel for some time.
Mine is an on-lan ZFS replication target for my main NAS, i.e. overnight low power local part of my backup strategy. I always knew it was not performing to it's full potential but it doesn't fall over.
The biggest challenge I had was getting OpenMediaVault 6 on it with the ZFS plugins from the extras repository. The upgrades around those broke so often I ended up learning Ansible so I could script the steps I was doing by hand.
Also, because of the quirks and the "if it breaks, it's going to be painful" situation of it all, I stuck to running from the SD card, which I have an image of at a stable point on my main NAS.
Every once in a while I would try to move it all forwards to newer versions, when it doesn't go so well I flash the SD card from the image and start reading the forums, which is what brought me back here 😅
