Title:
  booting cloud image without initramfs broken

Status in cloud-init:
  Expired
Status in cloud-init package in Ubuntu:
  Expired
Status in cloud-init source package in Trusty:
  Won't Fix

Bug description:
  Booting without a initramfs was broken by the cloud-init change for
  bug 1353008 (http://pad.lv/1353008).

  This affects arm guests where a bootloader is not used that would load
  kernel and initramfs.

  There are 2 workarounds:
  a.) remove the offensive code
    sudo mount-image-callback ubuntu.img -- \
       sh -c 'f="$MOUNTPOINT/etc/init/cloud-init-local.conf";
              sed -e "/^start on/s/ and mounted .*//" -i.dist $f &&
              diff -u $f.dist $f'

  b.) register and boot with an initramfs
    This is done by
     i.) getting the initramfs out of the image:
       sudo mount-image-callback ubuntu.img -- \
         sh -c 'cp $MOUNTPOINT/boot/initrd* . && chmod ugo+r initrd*'
     ii.) upload the initramfs to glance
       glance image-create --name=ubuntu-ramdisk --public \
          --container-format ari --disk-format ari < initrd*
       record the ramdisk id
     iii.) register with --property ramdisk_id=$RAMDISK_ID
       normally for "ami" style images on arm, the user had been
       uploading with --property kernel_id=<kernel_id>.
       now, you need to upload with:
         glance image-create --name="$NAME" \
            --public --container-format ami --disk-format ami \
            --property "kernel_id=$KERNEL_ID" \
            --property "ramdisk_id=$RAMDISK_ID" \ < ubuntu.img

   c.) register 'kernel command line' to include 'rw'.
       glance image-create .... --property kernel_args="root=/dev/vda rw"
