JFFS2 has been modified to sit on top of UBI.  

One thought here is that I would think that mounting is a fairly rare

I am probably missing something here, but how can UBI be useful by

1. Has lots (gigabytes) of flash
2. Must be power-fail safe.
3. Must boot in seconds even after power cycle
4. Does not have internal battery or super-capacitor to allow for sync

I hope UBI+UBIFS will be able to do that but it is not ready yet.
possibility is logfs but it is not ready either.

Sorry if that is a bit off-topic.
