Comment 11 for bug 1852518

Systemd upstream's position is that udev is not supported in containers which makes it practically impossible to support it in Ubuntu only. Nor should livecd-rootfs collect all the trick to keep image building tools operable in containers somehow.

I suggest applying the workaround in LP to get image builds going now with the current LXD in VM setup and going forward implement running livecd-rootfs in VMs instead of in privileged containers in VMs (running a different release of Ubuntu compared to the container).

I also suggest adopting the policy of not accepting any component to the Ubuntu images that can't be installed in a chroot. This also helps in better isolation of the built image from the build environment.
