Since observing a SquashFS image outperforming others when doing PDB database processing, I await Linux boot images to all switch to compressed read-only filesystems. Kernel image files already use bzimage for a long time. That would make it boot much faster, and use less memory than ISO: https://blog.sigma-star.at/post/2022/07/squashfs-erofs/ https://blog.sigma-star.at/post/2022/07/squashfs-erofs/ First step of system installation on Ubuntu (Debian) is uncompressing the filesystem. Why not use compressed FS for this purpose too, and shorten the whole process to few seconds?
