The other question is why use GRUB on a modern system? UEFI boot managers are far simpler to work with than GRUBs monster configuration file and in that case it makes sense to combine /boot with the ESP and use VFAT for it. As for the original question, AIUI ext2 was recommended more because there was no need for ext3/4 and journalling on such a small filesystem, rather than there being any compelling reason for not using ext4, so use what you want. -- Neil Bothwick Microbiology: staph only.
