Like cramfs? On the other hand, if I want the application directory tree to reside in memory (and handle application persistency needs via the JFFS2 partition), maybe all I need is to keep a compressed tar image of the application on the flash, and untar it into /my/application/partition, which will be in initramfs? So I don't need to create another tmpfs filesystem as suggested in another post?
