    I think we have here two cases:
    1. "A block of non-volatile RAM separate for normal system memory",
    [documentation Pramfs] and
    2. The whole RAM is non-volatile and so the whole situation is changed,
    and an NVM Mapping API is needed and "hotly" discussed.

    For 1. your solution is a very good concept that is getting around
    issues solely related with specific optimizations for disc-based file
    systems, like the 2 problems described in the documentation of Pramfs, but
    for 2. there is no need for a file system anymore, as we use it today
    while working with a computer system, because data needs not to be
    written to a file system at all, and so the file system will become
    something like a backup system in the most common use cases of a
    computing device, if I should describe it a little bit too provocative.
    In this case your approach taken to handle the 2 problems mentioned in
    the documentation of Pramfs would have to be driven further by focusing
    more on the management of the RAM, the power, and the long-term data
    storage (backup) for harmonizing Pramfs with them. A further point is to
    make Pramfs bootable, if this not already possible somehow.
