Some software titles may not be supported on RISC-V in general, or because no RISC-V binaries or packages are provided yet. Most of these cases have been identified already and related software titles have been disabled for the RISC-V architecture for now.

Other software titles may only be unsupported on the particular VisionFive 2 SBC, or the kernel build we use. This is known for Docker, likely other container engines, the NFS server and the SMB client, but there may be more. We aim to generate own kernel builds, with added features the next week(s). Any help to create an rebase a fork on latest upstream Linux 5.15 is highly appreciated.

Again other software titles may not be supported with latest PHP, Python and other runtime environments and libraries, provided by Debian Sid. The RISC-V architecture is not yet officially supported by Debian, but only with the dedicated Debian ports repository and Debian Sid/unstable suite. Currently, this mostly equals Bookworm, which is the reason DietPi identifies as this. A list of software titles tested on Bookworm can be found here: https://github.com/MichaIng/DietPi/wiki/Debian-Bookworm-testing
