X86 64
Ubuntu Server 22.04 LTS is the obvious candidate. And has the additional bonus of a supported real time (RT) kernel. Another candidate is Ubuntu Server 23.10, with a newer kernel and more up to date drivers.
Raspberry Pi 4/5
Bookworm aarch64 Lite (without desktop) SO installation is faster than Ubuntu, with a newer 6.1 kernel but there are more outstanding issues. Ubuntu Server 22.04 64 Raspi SO installation is much, much slower than Bookworm, but everything works on an old 5.15 kernel. Other candidates include Ubuntu 23.10 Server 23.10 and 32 bit versions of Bookworm and Ubuntu Server Raspi.
While Ubuntu 22.04 Raspi works as it is, I am concerned by issues with installing CamillaDSP and building a RT kernel. (Have successfully built RT Kernels for Ubuntu Server 22.04 and Bookworm aarch64 Lite). While these issues should not affect most SO users, I feel that Ubuntu Raspi's much slower development path could hold back the evolution of SO.
My preferences for Measurements 1.3.x are X86: Ubuntu Server 22.04 LTS with supported RT kernel and Pi4/5: Bookworm aarch64 Lite.
