There is no difference, that's exactly what I was talking about. =20
The alternative is to boot and load a kernel from the usb widget, and
have the pre-chroot root in an md image bound into the kernel. The
usb widget isn't mounted or needed after the kernel has loaded, and
chroot-root is mounted from cgd on the hard disk.
But I'm quite sure you know that, so we must be talking at cross
purposes somehow. What scenario were you envisaging where actually
mounting the usb device as the root filesystem (either before or after
chroot) was desired?

I think this is a separate issue, regardless of where things are
