The > “guix system” is still a bit mysterious to me… Yeah, guix system in essence "just" builds a disk-image (aka vm-image).

Maybe you had bad luck/try again? Does `herd start ssh' work after you login as root? It could be that your "bad luck" comes from qemu networking -- maybe you could try running your foreign distro's qemu instead of guix's? > Then, > > login> login root RET RET > root@guixygnu ~# $(guix build hello)/bin/hello > > downloads, builds, and displays as expected “Hello, world!”. \o/ \o/ > Last, I am confused: > > debian$ guix build hello --target=586-pc-gnu hello > /gnu/store/09sz4qsqp3zgnbaxhzppspaxihwmfzll-hello-2.10 > > root@guixygnu ~# guix build hello > /gnu/store/<other-hash>-hello-2.10 > > What do I miss? It's tricky; --target is != --system: --target is a cross-build. IOW, --system => (%current-system), --target => (%current-target-system). So, guix build hello --system=i586-gnu hello should give the identical hash. > (Sorry for these naive questions.) You're welcome. Thanks for looking at this! > Thank you! All is really neat! Hehe, that's what we are doing it for; Have fun!
