<desperate plea> Come on guys (and gals). Am I championing a lost
cause here? Have we given up on power down reliability of nonvolatile data in embedded systems under Linux?

Power down reliability of such data is an absolute must.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ THANK YOU, THANK YOU, THANK YOU!!!!

I expect embedded
systems using NFTL and ext3 to be absolutely reliable even if the plug is pulled half-way through a write.

This means we end up with two separate journalling / logging mechanisms - one at the block device level (ext3) and one at the flash media level (NFTL). As I said - ideally, we ditch that in the end and have a journalling/log-structured filesystem directly on the flash media.
