Wear-leveling and Journaling file system for NOR flash?

What are folks using for reliable file system on
for example SST26VF064B 64Mbit SQI flash?
Naive FAT will quickly wear out device for some uses;
needs a wear-leveling file system.
Needs to be power-off safe as well; no corrupted
file system from arbitrarily-timed power cut.
Anybody?
Thanks,
Best Regards, Dave

PS: A customer of ours used TINY by HCC some years back.
It is unfortunately neither very well performing nor stable;
led to product recall because it didn't properly wear-level
and flash devices failed...

might be a good start to select another flash file system.

The cool kids seem to be using spiffs, for smaller systems anyway.
