> The main use case for qemu-user is.. running programs for one CPU architecture on another.. most people don’t realize that you can run a qemu-user emulator which targets the same architecture as the host.

True, but still neat. Frankly I think this kind of functionality should be built in to OSs. Why shouldn't I expect to be able to run code written for the same OS on two different architectures without recompilation?

  The kernel supports that via the binfmt_misc feature. On Debian you just have to install the packages: https://wiki.debian.org/QemuUserEmulation https://wiki.debian.org/QemuUserEmulation
