For an ESP, I don't think I've ever seen a recommendation of less than 100MB. Some bootloaders newer than Grub2 are dubiously designed to load kernels & initrds from the (FAT!?!?!!!! — no symlinks possible!) ESP, leading to vastly larger ESP size recommendations. I created this one 7 years ago: # df -h | grep boot /dev/sda1 320M 21M 299M 7% /boot/efi # At that time, ESP minimum was 100M, unless using 4k sectors on a boot disk larger than 16T, in which case it was 260M. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
