** Attachment removed: "script that does download for easy test" https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1688606/+attachment/4872380/+files/prepare-1688606.sh
** Description changed: === 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. $ [ "$(lsb_release -sc)" = "precise" ] && - echo "manual_add_modules squashfs" | - sudo tee /etc/initramfs-tools/hooks/squashfs + echo "manual_add_modules squashfs" | + sudo tee /etc/initramfs-tools/hooks/squashfs 2. install cloud-initramfs-rooturl sudo apt-get update sudo apt-get install cloud-initramfs-rooturl 3. collect the kernel and newly generated initramfs sudo cat /boot/vmlinu?-$(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.
