Why does your tool need to run from the boot partition?
It does not. But it needs to run setuid root, and this seems not to
work on FireWire-non-boot-partitions.
Of course. Otherwise, I could take a FireWire drive, hook it up to my
Mac, put a tool on it, make it setuid root, then connect my drive to
your Mac and boom! Instance root access.
Well, if you near enough to my machine to insert a FireWire cable,
then you are also able to insert a boot-CD.
But I agree: mounting external partitions with MNT_NOSUID = "don't
honor setuid bits" is probably a good idea.
