ok, I will not pursue jffs2.

Yes, as soon as I find out the state of NFTL. I got a little scared by the
following comment in the howto:

quote: "DO NOT EVER USE THE nftl_format UTILITY WITHOUT FIRST SEEKING ADVICE
ON THE MAILING LIST. It will erase all blocks on the device,
potentially losing the factory-programmed information about bad
blocks. (Someone really ought to fix it one of these days - ed)"

Does NFTL include wear leveling and/or bad block remapping?
