A proposal, adding an (identical) note to 6.3.4.2 (guided partitioning) and 6.3.4.3 (manual partitioning), two places, where we are talking about ESP: ---------------------------------------------------------------------------------------- To be future-safe, you should not go with an ESP partition smaller than 768-1000 MB these days. Otherwise you risk running into problems, when it comes to kernel upgrades via UKIs or firmware upgrades of your PC's devices later. By the way: the same size recommendation counts for /boot as well (if you spend a separate partition for /boot). ---------------------------------------------------------------------------------------- Since we have a similar issue with /boot, I have added the second sentence, BTW.
