**What is left for initial support (32-on-64) is**
* Fixing bugs :)
**For pure 64bit support, we need to**
* bootstrap a distrib
* port gdb
* Fix bugs :)
* Notably it seems to be requiring at least 2G memory to boot.
**Installing a 64bit chroot**
You can use the pre-built image from https://people.debian.org/~sthibault/hurd-i386/initrd-amd64.img.gz and boot that.
Make sure to have `debootstrap >= 1.0.128+nmu2+hurd.1`
debootstrap --foreign --verbose --arch hurd-amd64 --include=debian-keyring,wget,curl,inetutils-ping,openssh-server,openssh-client,nano,less --keyring=/usr/share/keyrings/debian-keyring.gpg sid chroot-hurd-amd64 https://people.debian.org/~sthibault/tmp/hurd-amd64
mkdir chroot-hurd-amd64/etc/apt/trusted.gpg.d
ln -s /usr/share/keyrings/debian-keyring.gpg chroot-hurd-amd64/etc/apt/trusted.gpg.d/
Then boot it, it will drop you into a shell. You need to make / writable:
fsysopts / --writable
and then run the second stage of the deboostrap (and clear debs):
/debootstrap/debootstrap --second-stage
apt clean
set a root password:
passwd
Avoid core dumpings for now (not supported and hangs):
rm -f /servers/crash
ln -s crash-kill /servers/crash
Disable the Hurd console, buggy for now:
export TERM=mach
nano /etc/default/hurd
# set ENABLE to 'false'
And reboot:
reboot-hurd
After reboot, you'll probably want to setup network:
vi /etc/network/interfaces
# put there this:
# auto /dev/eth0
# iface /dev/eth0 inet static
# address 10.0.2.15/16
# gateway 10.0.2.2
**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
module /hurd/pci-arbiter.static pci-arbiter \
--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)'
}
EOF
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.
**Installing from the debian-ports archive**
For now it's quite empty (not even gcc), but it can be debootstrapped. That will be used to build packages on the buildds.
debootstrap --foreign --verbose --arch hurd-amd64 --extra-suites=unreleased --include=debian-ports-archive-keyring --keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg sid chroot-hurd-amd64 https://deb.debian.org/debian-ports/
**Installing a 64bit system**
In principle crosshurd should be working, one however should add this source to get more packages for now:
deb http://people.debian.org/~sthibault/tmp/hurd-amd64 unstable
into /etc/crosshurd/sources.list/gnu
