+**Creating a 64bit disk image**
+
+You can use the pre-built image from https://people.debian.org/~sthibault/hurd-i386/disk-amd64.img.gz and boot that.
+
+To make a bootable system we really better make the disk image partitioned, and mount the partition:
+
+ dd < /dev/zero > disk.img bs=1M count=1 seek=1000
+ fdisk disk.img
+ # create a new primary partition spanning the whole disk: n p and just accept the defaults, and finish with w
+ settrans -ca disk /hurd/storeio -T typed file:disk.img
+ settrans -ca disk1 /hurd/storeio -T typed part:1:file:disk.img
+ mke2fs disk1
+ settrans -ca chroot-hurd-amd64 /hurd/ext2fs disk1
+
+(here we assume that fdisk puts the partition at sector 2048, that's indeed the
+current default behavior)
+
+Then run the same debootstrap command as above.
+
+You can then make the disk bootable:
+
+ mkdir chroot-hurd-amd64/boot/grub
+ tee chroot-hurd-amd64/boot/grub/grub.cfg << 'EOF'
+ menuentry "Debian GNU/Hurd amd64" {
+ insmod ext2
+ set root=(hd0,1)
+ multiboot /boot/gnumach-1.8-486.gz root=part:1:device:wd0

+ --host-priv-port='${host-port}' --device-master-port='${device-port}' \
+ --next-task='${disk-task}' \
+ '$(pci-task=task-create)' '$(task-resume)'
+ module /hurd/rumpdisk.static rumpdisk \
+ --next-task='${fs-task}' \
+ '$(disk-task=task-create)'
+ module /hurd/ext2fs.static ext2fs --readonly \
+ --multiboot-command-line='${kernel-command-line}' \
+ --exec-server-task='${exec-task}' -T typed '${root}' \
+ '$(fs-task=task-create)'
+ module /lib/ld-x86-64.so.1 exec /hurd/exec '$(exec-task=task-create)'
+ }

+ grub-install --modules="part_msdos ext2" --boot-directory chroot-hurd-amd64/boot disk
+ settrans -ga chroot-hurd-amd64
+ settrans -ga disk
+ settrans -ga disk1
+
+Note: you need to set the uuid in the grub config according to the uuid produced by the `mke2fs` command.
+
+Then boot it, and proceed like for the chroot case.

In principle crosshurd should be working, one however needs to add this source:
