Hello,
Is there an update about implementing a read-only file system on NAND? The
most recent discussion I could find was from May 2012:
http://lists.infradead.org/pipermail/linux-mtd/2012-May/041200.html
The conclusion seemed to be to use ubi underneath something like squashfs to
provide bad-block awareness. Is this still the recommended solution?
Thanks,
Rod Campbell

Yes. Using the new UBI block driver this is trivial.
