Hello Jan,

Yes that's an issue.

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)?

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?

Great to see you so close :)
Thanks,
Mathieu
