I would like to create the smallest jffs2 file system possible.  We
want to have a small separate mount point to store a small number 
(<5) of small text files (<1k each).

Empirically I've determined that this minimum size is effectively 5 *
N, where N is the physical erase block size of the underlying flash
part.  Is this correct?  Are there any workaround or patches to enable
building a smaller file system?  Is a different f/s recommended for
such an application (must be r/w, don't care about compression
particularly).

Thanks,
Kylo

JFFS2 always reserves several blocks for GC. So I doubt you can create
smaller FS without hacking.
