I didn't take notes, but off the top of my head something like this:

  Booted the OE image that shipped with it on the microSD

  add partition for new rootfs (cfdisk /dev/mmcblk?)

  mkfs.ext4 /dev/mmcblkXpY
  mount -o noatime /dev/mmcblkXpY /mnt

  git clone https://salsa.debian.org/installer-team/debootstrap
  cd deboostrap
  sudo DEBOOTSTRAP_DIR=$(pwd) ./deboostrap --arch=riscv64 sid /mnt http://deb.debian.org/debian-ports
  echo 'UUID=...  / ext4 errors=remount-ro 0 1' > /mnt/etc/fstab
  echo 'tmpfs /tmp tmpfs defaults,nosuid,nodev 0 0' >> /mnt/etc/fstab

  sudo chroot /mnt adduser vagrant --gecos ,,,
  sudo chroot /mnt adduser vagrant sudo
  sudo chroot /mnt passwd vagrant

  add another entry to /boot/extlinux/extlinux.conf using the
  appropriate root=/dev/mmcblkXpY and/or root=UUID=...

Probably missed something, but that's the jist.

Then, to build guix...

  git clone https://salsa.debian.org/debian/guix/
  cd guix
  git remote add originguix https://git.savannah.gnu.org/git/guix.git
  git fetch
  git format-patch -o debian/patches originguix/master..originguix/wip-riscv
  # add new patches to debian/patches/series
  
  # adjust debian/rules and debian/control to use guile-3.0...

  # build the package!
  DEB_BUILD_OPTIONS='nocheck parallel=5' sbuild --chroot-mode=unshare -d UNRELEASED -c sid 

Upgrading to use guile-3.0 required a manually rebuilt guile-gnutls
against guile-3.0 as well...

Just pushed debian/wip-riscv64 to https://salsa.debian.org/debian/guix/
if you want to look at my most recent attempt.

Notably, this is just the wip-riscv patches applied against guix 1.3.0;
maybe building against guix master will be more successful?


live well,
  vagrant
