exfat-utils-1.2.8-2.fc28.x86_64

I have an 256GB sdcard, the original filesystem was was exFAT, and the original volume serial number was 0x00000000, I wanted to recreate that.

mkfs.exfat -i 0 /dev/sdd1
mkfs.exfat -i "0" /dev/sdd1
mkfs.exfat -i 0x0 /dev/sdd1
mkfs.exfat -i "0x0" /dev/sdd1
mkfs.exfat -i 0x00000000 /dev/sdd1
mkfs.exfat -i "0x00000000" /dev/sdd1

All appear to silently ignore the -i option when given different versions of 0, and behave as if the -i option wasn't given. After giving each of these commands, a randomly generated 32-bit hex number is assigned. 0x00000000 is a valid 32-bit hex number, there is nothing in the man page stating that it's an invalid volume serial number, and mkfs.exfat doesn't produce an error message, it just silently ignores values of 0.
