It seems like there are quite a few new and upcoming devices making use of NAND flash exclusively. If squashfs (which according to me has been the filesystem of choice on my openwrt installations) is not it good shape, are we throwing in the towel? Surely, there must be some hope for OpenWrt users for these new devices. Regards, Chirag
