At FOSDEM'17, Manolis [cc] inspired me with his talk to have a look at
HURD and help.

Sadly, the above recipe is all the help I found to offer until now, but hey.

That's how I feel too.  Guix should make working together on a project
like Hurd a lot easier.

I'm sure the recipe has bitrotten a bit, esp. names of branches and
hashes; it would be great if you could try it and help keep it up to
date.

Thank you Jan for sharing these precious notes!

I've saved your message; I had started looking into Hurd last year, but
then turned my attention to Guix and have been (slowly) making myself at home 
here. I
intend to restart investigating Hurd as things stabilize on the Guix
side :). They are destined to work together anyway ;)

Helping with Guix on Hurd: my notes

2017-02-17 Thread Jan Nieuwenhuizen 
Hi,

I have just successfully built

./pre-inst-env guix package -i hello --keep-failed

on Debian/Hurd.  Find my notes below.

* Help with Hurd  -*- mode: org 
-*-

In his talk @FOSDEM'17

https://fosdem.org/2017/schedule/event/guixhurd/

https://fosdem.org/2017/schedule/event/guixhurd/attachments/slides/1850/export/events/attachments/guixhurd/slides/1850/guix_to_hurd_fosdem_2017.pdf

Manolis sends out a call for help to get Hurd supported in Guix.  A lot
of work has been done.  Some bigger things remains, and there is also a
lot of small, simple things to be fixed.  So, get involved!

* Setup Guix build environment on Debian/Hurd

** Get Hurd image from Debian
*** Entry: https://www.debian.org/ports/hurd/hurd-install
*** Next: https://people.debian.org/~sthibault/hurd-i386/

wget http://people.debian.org/~sthibault/hurd-i386/debian-hurd.img.tar.gz
tar xzf debian-hurd.img.tar.gz

*** Boot it
qemu-system-i386 -enable-kvm -drive 
file=debian-hurd-20170115.img,cache=writeback -m 1G -net 
user,hostfwd=tcp:127.0.0.1:2223-:22 -net nic

*** Create additional storage

qemu-img create -f raw gnu.img 30G
fdisk gnu.img
mkfs.ext2 /dev/hd1s1

*** Setup fstab: TRAMP /ssh:root@hurd#2223:/etc/fstab

# /etc/fstab: static file system information.

*** [@hurd] Create user

adduser janneke sudo
passwd janneke

*** [@GuixSD]: Add to .ssh/config
Host hurd
   HostName localhost
   Port 2223
   ForwardAgent yes

*** Build bootstrap binaries

git checkout core-updates

*** [@hurd] Prepare to build Guix
 Checkout Guix

sudo apt-get install git

git clone gnu:guix.git
cd guix
git remote add phant0mas g...@github.com:Phant0mas/guix-on-hurd.git
git fetch phant0mas
git checkout wip-hurd-native

 Add Debian build dependencies
sudo apt-get install build-essential dh-autoreconf dh-systemd autotools-dev 
graphviz guile-2.0-dev guile-json help2man libgcrypt20-dev libsqlite3-dev 
libbz2-dev texinfo

 Add Hurd bootstrap binaries
mkdir -p gnu/packages/bootstrap/i586-gnu

** [@GuixSD] Start qemu: additional resources: 4G of memory, 30G storage:
