MFS == memory filesystem; aka ram-disk. The problem being that on reboot, MFS looses all its contents, therefore practices like storing the 'startup' state for a filesystem in an archive (tar file works well) and mounting/copying on startup works well. Conversely, if you need to modify that startup state you can just over-write the tarfile again.
