Public bug reported: === 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] 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. $ 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.
