Compressed images for container or chroot use have been reduced to approximately 30MB , but these lack a kernel, init system, and graphical interface.
Highly stable and considered one of the fastest versions tested, though it requires a 2 GHz dual-core processor and 4 GB of RAM . ubuntu highly compressed 10mb
In short, even the absolute minimum bootable Linux system (kernel + init + a shell) is around compressed. That’s without networking, package management, or any Ubuntu identity. A 10MB target is physically impossible for a general-purpose OS. Compressed images for container or chroot use have
# Use Alpine Linux's mkimage script but swap alpine-apk for ubuntu's libs # This creates an initramfs where the root is compressed in RAM but these lack a kernel
