 Installation Caveats
- If you use olpcflash to write this image, you must use the --brick option.
- After you reflash, you must power cycle by physically removing power from the system. A warm-start or button-induced restart is not sufficient.
 Known issues
- Auto-repeat is slow on some USB keyboards
- NVRAM storage for configuration variables is not yet implemented.
- JFFS2 does not pay attention to the bad block table.
- JFFS2 does not handle ECC
- The boot menu is incomplete
- Dirctory symlinks have a problem.
