Comment 33 for bug 1235231

Using a build from current lp:ubuntu/plymouth that has steve's fix for bug 1160079 inside it, I no longer am losing data written to the console!

I've tested this in a trusty kvm local image.
disk-patched.img had the new debs installed
disk-unpatched.img did not.
both images had https://bugs.freedesktop.org/attachment.cgi?id=89759 run on them (so the logging init-wrapper was in place).

$ cat go-test.txt
LOG="out.log"
rm -f "$LOG"
i=0
while i=$(($i+1)) && [ $i -le 10 ]; do
  echo "---- $(date) $i ----" >> "$LOG"
  for r in patched unpatched; do
    qemu-img create -f qcow2 -b disk1-$r.img disk1.img
    slog=$(printf "serial-%s-%02d.log" "$r" "$i")
    echo "---- $(date) $i $r ----" >> "$LOG"
    kvm -net nic -net user,hostfwd=tcp::2222-:22 \
       -drive file=disk1.img,if=virtio -drive file=seed.img,if=virtio \
       -serial "file:$slog" -vga none -nographic
  done
done

echo "--- $(date) FINISHED ---" >> "$LOG"

$ cat user-data
