262 if you include the flags of England, Scotland, and Wales, which for some reason are the only flags in their own separate blocs.

This is not a GPU, this is a laptop SoC with CPU and integrated GPU, and knowing nvidia it will probably be even more closed than an intel CPU. You will own even less of your hardware

Nearly all ARM CPUs are "even more closed than an intel CPU" on a driver level. Nvidia stands out by supporting UEFI on ARM, which even Apple refuses: https://docs.nvidia.com/dgx/dgx-spark/uefi-settings.html

I'm not completely sure, but are cloud versions of the distros actually recompiling the packages ?

I though it was mostly: "select a minimal set of packages needed for docker and co", not "recompile all the packages you want in your distro".

Don't know actually, it might be I they are just putting cloud-init in, installing their VM agents, and maybe like tweaking the bootloader setup and kernel cmdline or something. But equally, they might be compiling it themselves so they don't have to trust distros' build farms so much.

But anyway I don't think it matters. The hard part here is having a distro image supply chain, not compiling stuff. If they do need to start compiling loads of stuff they didn't before... They just need to add CPUs.
