as some of you might have learned, i'd like to import my work on NiLFSsupport. NiLFS stands for New implementation of Logging File System; ...It is said to perform very well on flash media since it is not overwriting pieces apart from a incidental update of the superblock, but that might change. It is accompanied by a cleaner to clean up the segments and recover lost space.
That's a fatastic news. How well the on-disc format copes with bare NAND chip parametrics; say 512B small NAND case and/or 2048B large NAND case? It's fairly easy and pretty economical to use bare NAND chip for embeded NetBSD rootfs. The design issue is wear-leveling, asymmetric nature of erase/write size and bad block management. How is NiLFS approaching? Toru Nishimura / ALKYL Technology
