[Merge] ~rbalint/livecd-rootfs:empty-fstab-in-lxd into livecd-rootfs:ubuntu/master

[Balint Reczey]

Systemd 245.6-1ubuntu1 needs to land in groovy's release pocket first to not break the systemd autopkgtest.

I verified that the fstab is now missing and that LXD container boots perfectly without /etc/fstab.
Is there any place where the squashfs is converted back to an image where label originally present is relied on? Those places should be fixed.
