Since exFAT support was enabled, mounting an iso9660 filesystem prints spurious exFAT errors to the console. That is because busybox mount tries all filesystems in the order listed, and exfat precedes iso9660 (those are the last two in our config). Most filesystems are silent when used on the wrong type of filesystem, but exFAT logs errors, which appear on the console. Move exFAT after iso9660, so iso9660 filesystems won't show these errors. The errors will still appear if the filesystem is actually exFAT but cannot be mounted. There's no significant risk of misdetecting a remnant iso9660 superblock here either. Although an iso9660 superblock could fall in the unused space between the exFAT boot region and the FAT itself, mkfs.exfat does zero this space so it is unlikely such a remnant superblock would exist.
