See: http://www.linux-mtd.infradead.org/faq/ubifs.html#L_empty_file Please let me know whether this helped. I guess mounting UBIFS in sync mode is what you want. But please also keep this in mind: http://www.linux-mtd.infradead.org/doc/ubifs.html#L_sync_semantics Thanks, //richard _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
