Ok. So a bit more digging and Bayou looks like something worth looking
rather than FILO CBFS support.

Drawback is that it looks like Bayou is not really CBFS friendly right
now and sort of duplicates some functionality that you get with CBFS too

Also, this means ending up with effectively a minimum 3 payloads in
precious Flash rather than 2 (Bayou + Payload2 + (FILO --> /dev/hda)) Vs
((FILO --> /dev/hda) + Payload2)

Hmmmm. Think I still like the idea of direct CBFS support in FILO.
