[Yaffs-archive] Re: YAFFS softlink bug?

The process seems to be:
1) yaffs built with CONFIG_YAFFS_GENERIC_RW asserted
    Copy a pair of files libxx and libxx.y to a yaffs directory (where
libxx.y is originally a softlink).
    This copies both as files as the link is followed.
    Delete libxx.y
    Recreate libxx.y as a softlink - it seems important that the filename is
the same.
    "ls -al libxx*" now has an error saying that "libxx.y cannot be found"
1) yaffs built with CONFIG_YAFFS_GENERIC_RW commented out
    Same as above
    No problems.
