Hi, I've found that d-i creates /boot as ext2 for guided partioning with LVM. I think ext4 is better but is there any reason to do so? (e.g. some architecture or bootloader cannot recognize ext4 for it) If not, I'll prepare a MR for it. (Of course, it will be treated after bullseye release). -- Regards, Hideki Yamane henrich @ debian.org/iijmio-mail.jp
