EFI System Partition: Using it as /boot versus /boot/efi
by MirceaKitsune from LinuxQuestions.org on (#5G77Q)
This is a more generic Linux question. As I have an EFI motherboard with Secure Boot I need an ESP partition: I have one mounted as /boot/efi and it works fine on this installation. But I was wondering; Is there any disadvantage to making the entirety of /boot my ESP? That way I can make better use of the 4GB I assign to it, having it store grub and the kernel images too... they're all loaded temporarily as part of the boot process so it makes sense to use this one little partition for everything! As long as it's fat32 there shouldn't be anything breaking the configuration right? Especially on a machine where I don't plan to dual-boot, only one OS installed on the main drive so there would be no kernel image conflicts.
Just in case though I wanted to ask for opinions: Does anyone else place the entirety of /boot on the EFI partition instead of just /boot/efi? Does it work well for you, do you find it more optimal this way? As a bonus question; Is exfat (fat64) a newer and better partition format to use, or is it still a good idea to stick to fat32 exclusively for the ESP else the BIOS might complain?
