JFFS2 has been modified to sit on top of UBI.

One thought here is that I would think that mounting is a fairly rare
occurance.
You're much more likely to coming back from suspend. Notice the
difference in time it takes from my HP iPAQ to power-on normally vs a
cold boot. It is very different.

Hello,

I am probably missing something here, but how can UBI be useful by
itself?
I would think until UBIFS is ready there is not much one can do with it.
Please tell me I am wrong ;-)

I am not aware of any non-commercial solution that can be used on a
system
that:
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
on
power failure.

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

Sorry if that is a bit off-topic.

Regards,

Sergei Sharonov
