Yeah. Using a journalling pseudo-filesystem to emulate a block device, and 
having to set aside a hunk of the space it provides for journalling of a
'normal' file system, is crazy. IMHO, you only have an excuse for pretending
that flash is a block device if you're still running DOS.

The JFFS2 NAND support is almost complete -- just a few corner cases to be 
fixed up. AFAIK it should work on DoC without too much trouble -- after 
all, a DoC is just a bunch of NAND flash chips.
