Rough Notes

This process will be reduced over time, and merged into either poudriere-image(8) or the official FreeBSD release process.

This creates a efi.qcow image, which you should rename to include date of build & truncated sha of commit:

  • FreeBSD-14.0-CURRENT-arm64-aarch64-20211026-a40784e-rescue.qcow2

This image (currently) is manually modified and a functioning zroot.zfs appended to it - hacky but quicker than perfecting poudriere image at short notice.

appending a working zroot

This is probably correct, but done from rough notes.

# truncate -s 5G efi.fat
# mdconfig -u md99 efi.fat
# gpart add -t freebsd-zfs -a 1m -l zfs0 md99
# zpool create \
  -o failmode=continue \
  -O atime=off \
  -O compression=zstd-9 \
   -O checksum=skein \
  -R /mnt \
zroot /dev/md99p2
# zfs recv -Fuvs zroot > /some/existing/zroot.zfs
# zpool set bootfs=zroot/ROOT/default zroot
# zpool export zroot
# mdconfig -du md99
# qemu-img convert -c -p -f raw -O qcow2 efi.fat FreeBSD-14.0-CURRENT-arm64-aarch64-20211027-a40784e-phat.qcow2

building tarballs

These are built in the usual way from https://git.sr.ht/~dch/src/tree/works-on-my-machine which is https://cgit.freebsd.org/src/commit/?id=1fec1fa and a further few commits, only one of which is still needed. I built these on FreeBSD arm64, not amd64.
