Is that our package of packer.io that we'd want to adapt or a PR for upstream maybe? - -Also misfiled against upstream's Qemu - this clearly was meant for Ubuntu's Qemu as technically upstream is still fine enabling sdl (if the package builder wants to). - -Changing the bug tasks ... - -Ha, Thomas beat me to re-target the bug while I was checking my inbox - thanks :-) - -Thanks for the explanation. MAAS is starting to use Packer to create custom images so we may be packaging this soon.
