You also need to make sure
/tmp/UNRAID/syslinux/syslinux_linux
is executable (
chmod +x
). I would
chmod -R =X /tmp/UNRAID/syslinux
the whole folder.
Regardless of using FAT32, this worked for me. There REALLY need to be a dedicated page for this if there is not one. a Linux based distro not having an easy Linux based install. That just sounds weird.
