+\section{JFFS3 goals and requirements}
+The following is somewhat unstructured list of JFFS2 goals and requirements.
+
+\begin{enumerate}
+\item Fully POSIX-compatible file system.
+\item The main OS is Linux (TODO: nonetheless portable?).
+\item Good scalability.
+\item Preserve the possibility to efficiently use compression (like in JFFS2).
+\item Provide good wear-leveling.
+\item Tolerant to unclean reboots.
+\item Fast mounting.
+\item Reasonably low memory consumption.
+\item Fast enough read/write operations.
+\item Support different Flash types (NOR, NAND, etc).
+\item Support xattr.
+\end{enumerate}
+
+Of course there are a number of tradeoffs and we should find a balanced compromise
+solution,
