Well... using an inode-based filesystem like ext2 or ext3 is a really bad idea, since you end up rewriting some of the blocks a *lot*. Journalling the metadata, as ext3 does it, does make things even worse as you say. Using a purely journalled FS like jffs2, on the other hand, is a really good idea since it's designed to avoid exactly those flaws. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
