The entire USB drive should probably be mountable as type iso9660 or
udf. The vast majority of things that can boot from USB drives will
recognize ISO images that have been dd'ed directly to the disk, and
that's how you usually boot from a USB drive. unetbootin is almost
certainly just doing "dd if=/path/to/linux-mint-12.34.iso of=/dev/sdX
bs=1M" behind the scenes.

(I did see something odd a few days ago when trying to diagnose a
completely different problem. I dd'ed a Gentoo net install image to a
USB disk, then booted the machine from that disk. The installer loaded
its initrd, then said that it couldn't find the root filesystem. I
tried several device names and got nowhere, though 1 of them should've
worked. It might have been confused by the larger-than-usual number of
disks attached to this machine, or might've forgotten to do "modprobe
ehci-hcd". Will attempt to figure this out later.)
