    Depends on how much time and money you got for this project.
    If you have time I suggest that you bild your own distro.
    What is the CPU?

    JFFS2 is a great fs although it has some drawbacks. But for flash it's the perfect sollution.
    Usually on all embedded systems based on linux it's used in combination with cramfs (for the
    "read-only" part of the image ) and tmpfs for log, chaching and apps that need fast file ops.

    My experience shows that if you keep 10-15% of the jffs2 partition empty there won't be any
    problems.
