It also doesn't work worth a damn.  Believe me, I'm talking from experience
here.

Furthermore, it's basically a solution looking for a problem.  It is
*trivial* to arrange for your embedded device to write so infrequently
that wear-levelling isn't an issue (hint: if you're getting anything but
configuration information from a read/write filesystem, you designed your
software wrong), and besides, many increasingly common types of flash do
wear-levelling internally, for example all CompactFlash devices.

Of course, I suppose the Linux solution is to use CompactFlash and a
read-write JFFS root filesystem because, after all, it's more important
to use all the correct buzzwords than it is to actually have any clue about
what you're doing.
