USB device as root: What about updates ?

[OutOfRange]

Good morning out there.

I'm very new into Linux stuff, so there's something I'm worried about:
Since I had problems with corrupted SD-Cards three times, I'm using an USB flash memory as root. It contains exactly the same file structure as there is on the (still neccessary) SD-Card.

Since the boot partition is still used from the SD-Card and the root one is on the USB memory, might there be an issue when updating the firmware, that updates which belong to the SD-Card's boot partition are not written there and instead are placed on the USB's boot partition (which in fact is useless) ?

I'm using Adafruits Occidentalis V0.2.

Best regards from Switzerland

make sure you mount the SD card /boot as your /boot -no need to have that on the SD card

Works like a charm, thank you
