The type of flash that you should use jffs2 on are not going to support
a boot loader like grub/lilo. If you are using a CF card for example it
already has wear leveling and correction at the hardware level and
therefore ext2 etc are fine. If you are using a stick of NAND flash
from samsung that his registered by the system as a memory segment this
is when you need jffs2. In this case you need to see what the boot
properties of the device are (mine has a bios option to load a boot
loader from a particular location) then put the apporopriate code there.

Do you use initrd to bootstrap, or do boot loaders like lilo and grub
understand jffs2? I've been using ext2 on my CompactFlash simply because
I'm too lazy and haven't had time to learn how to use initrd.
