[Merge] ~simpoir/livecd-rootfs/+git/livecd-rootfs:lp2064175-jammy-buildd-grub-udev into livecd-rootfs:ubuntu/jammy

[Michael Hudson-Doyle]

I'm sorry I don't quite buy this as a fix for the problem. kpartx was never installed in the chroot. I also don't buy that this doesn't affect the artefacts as this hook creates the disk image artefact which is not modified by later hooks that I can see.

Do you have a link to a failing build?
