Bug description:
=== Begin SRU Template ===
[Impact]
MAAS has an interest in booting entirely ephemerally without iscsi root.
The package cloud-initramfs-rooturl supports booting with root coming
from a url.
root=http://..../squashfs
This function will be used to pxe boot into a RAM only system with no
dependency on the network.
[Test Case]
See the attached prepare-1688606.sh. That script automates
everything here making this much easier to test.
1. make sure squashfs module is in the initramfs
squashfs module is not automatically added to initramfs in precise.
Just ensure that it is there.
$ [ "$(lsb_release -sc)" = "precise" ] &&
echo "manual_add_modules squashfs" |
sudo tee /etc/initramfs-tools/hooks/squashfs
2. install cloud-initramfs-rooturl
sudo apt-get update
sudo apt-get install cloud-initramfs-rooturl
3. collect the kernel and newly generated initramfs
sudo cat /boot/vmlinu?-$(uname -r) > kernel
cp /boot/initrd.img-$(uname -r) initrd
4. Download a squashfs image or a .tar.xz image
rel="xenial"
burl="http://cloud-images.ubuntu.com/daily/server";
file="$rel-server-cloudimg-amd64-root.tar.xz"
file="$rel-server-cloudimg-amd64.squashfs"
wget "$burl/$rel/current/$file" -O "$file"
5. run a web server
python -m SimpleHTTPServer 9999 &
6. create a seed disk for cloud-init.
$ cat > my-user-data <<EOF
#cloud-config
password: passw0rd
chpasswd: { expire: False }
ssh_pwauth: True
$ echo "instance-id: $(uuidgen || echo i-abcdefg)" > my-meta-data
$ cloud-localds seed.img my-user-data my-meta-data
7. Boot a vm using the kernel, initrd and url.
cmdline="root=http://10.0.2.2:9999/$file console=ttyS0 -v "
cmdline="${cmdline} overlayroot=tmpfs"
qemu-system-x86_64 -enable-kvm \
-device virtio-net-pci,netdev=net00 \
-netdev type=user,id=net00 \
-drive if=virtio,file=seed.img \
-m 1G -nographic \
-kernel kernel -initrd initrd \
-append "root=$cmdline"
[Regression Potential]
Low. This is adding a package previously not present.
