My partition is fairly small so the mount time is OK right now, but I will
also be using a larger partition (about 3MB) later. Is anybody working on this
checkpointing thing? Could you explain the concept briefly?

It has worked fine for me this far.

Is it possible to "hide" a bootloader at the beginning of a jffs2 partition
so that jffs2 ignores it (when mounting read-only) and still be able to upgrade
the whole partition (bootloader + jffs2 fs) using the mtd character device?
