I'm never quite satisfied with the defaults, so I'm building a #bluefield2 install image using this tool.

It appears that it uses qemu to run aarch64 binaries using docker. I don't think I've seen this done before.

In any case, it takes a long time to build.

It's possible to build a couple of distros that I haven't heard of before.
#cytunos
#anolis
#bclinux

It looks like there are loongarch and riscv versions available
