It was reported and confirmed in LP bug #1875400 (https://bugs.launchpad.net/cloud-images/+bug/1875400) that on the public KVM cloud image there exists a large list of packages marked for auto-removal. This should never be the case on a released cloud image. These packages are marked for auto-removal because in the KVM image binary hook we removed both initramfs-tools and busybox-initramfs packages. Due to package dependencies this also removed: busybox-initramfs* cloud-initramfs-copymods* cloud-initramfs-dyn-netconf* cryptsetup-initramfs* initramfs-tools* initramfs-tools-core* multipath-tools* overlayroot* sg3-utils-udev* ubuntu-server* But it did not remove all the packages that the above list depended on. This resulted in all those packages being marked for auto-removal because they were not manually installed nor did they have any manually installed packages that depended on them. The removal of initramfs-tools and busybox-initramfs was to avoid the generation of initramfs in images that should boot initramfsless. This requirement is obsolete now because the initramfsless boot handling is now handled via setting GRUB_FORCE_PARTUUID in /etc/default/grub.d/40-force-partuuid.cfg. In test images I have verified that GRUB_FORCE_PARTUUID is set and that boot speeds have not regressed. LP: #1880170
