I have put some note on the wiki https://darnassus.sceen.net/~hurd-web/open_issues/64-bit_port/
to build a proper debian hurd-amd64 chroot: sudo debootstrap --foreign --verbose --arch hurd-amd64 --keyring=/usr/share/keyrings/debian-keyring.gpg sid chroot-hurd-amd64 https://people.debian.org/~sthibault/tmp/hurd-amd64 This most probably won't boot as-is for now (missing translator entries etc.), but that can be helpful to look at fixing startup bugs etc. Samuel
