Until last week, I had a full Debian amd64 systemd container to run invidious on an ARM64 machine (a ROCKpro64) running Armbian, since crystal (the language in which Invidious is written) does not have arm64 Debian packages. There's nothing special to make this work, regular commands work, for instance just running systemd-nspawn -b in an arm64 root folder works.

Now I found a way to get arm64 crystal binaries. I got rid of the container, but Invidious still cross compiles to amd64, so qemu is still used to run an amd64 build Invidious of transparently.

binfmt and qemu-user do wonders. It works well. One could use box64 [1] instead of qemu and it should provide better performance because it uses the native versions of some well known libraries (including libc6) instead of emulating them, but I failed to compile box64 this weekend so I stayed with qemu.
