1) Beware of featuritis. This is just a hack for the explained
problem, depends on the fs used (jffs2) and does not give any real new
functionality. Might be good for the sales department, though. :)
Yesterday, I scrambled a fs because it was recognized as jffs (1),
deleted and empty afterwards. Solution? Don't use jffs1 any more and
be smarter next time.
2) Flash is a write-once medium. You cannot overwrite the markers, you
have to delete again.
