JFFS2 is only used for the directly accessible flash, i.e. the 4Mb or
16 Mb of flash that's part of the gumstix. The flash stored on the MMC
card is written using a FAT file system by default, although you could
change it to use another (but you can't use JFFS2 on an MMC card).

Many people write to RAM disk (/tmp on the gumstix) for the frequent
stuff, and then less frequently roll it out to the MMC card.
