So nice & quick to have BT available on bootable USB. >> However, the 'changes' location -- as assigned in syslinux.cfg ... "APPEND ..... changes=/dev/sdb2" ... for example -- mean that a change in the boot machine's drive configuration, perhaps adding another USB attached drive -- means that the /dev/sdb2 assignment may no longer be valid, as the other USB drive may now be /dev/sdb2 and BT may be /dev/sdc2.

Tell me I am not seeing this correctly-- I would love to have a truly portable BT4 USB drive.
