I've experienced the exact same thing: Some months ago I attempted to build the Guix package for armhf-linux on my x86_64-linux machine (because there were no substitutes) using the qemu-binfmt service. I eventually gave up because it always got stuck (I tried it several times). In fact I tried it again today and it got stuck during the `build' phase running sed. Regards, Diego
