Creating an Empty JFFS2 File System

[Grant Erickson]

Is creating an empty JFFS2 file system supported or is this a deprecated
capability? The following steps seem to be incorrect or failing:

    # flash_eraseall -q -j /dev/mtd9
    # mount -t jffs2 /dev/mtdblock9 /mnt
    Cowardly refusing to erase blocks on filesystem with no valid JFFS2
    nodes
    empty_blocks 0, bad_blocks 0, c->nr_blocks 3840

Or, is the only way to accomplish this to create a NULL JFFS2 image with
mkfs.jffs2 and then nandwrite it?
