Well first this 'vm-image' thing should be done in (gnu system image) as soon as I have sorted out the bootloader issue. So the solution we will find to overcome this Hurd issue will be temporary I hope. About using qemu-TARGET, let say you are on an armhf machine and you want to cross-build an x86-64 image. I fear that using a native, armhf Grub to install an x86-64 Grub won't work. So maybe, it would be better to do that only for the architectures without an available qemu-TARGET (only the Hurd for now)? > ...the problem is now avoided by removing the sqlite dependency when > cross-building by not registering closures and postponing the loading of (gnu > store database) and thus (sqlite3). When I produce a system without register closures, once booted, "guix build" something does not work. I don't know if its possible for guix-daemon to work without its database. An option could be to generate this database if its absent, at first boot? > ./pre-inst-env guix system vm-image --target=i586-pc-gnu --no-grafts \ > gnu/system/examples/bare-hurd.tmpl > > now produces a pretty nice hurd VM :-) Great to see you so close :) Thanks, Mathieu
