Hello,
I installed Debian on my SheevaPlug following instructions at
<http://www.cyrius.com/debian/kirkwood/sheevaplug/> and everything
seemed to work fine until...
I wanted to try UBIFS on the built-in flash and followed
the instructions for formatting the internal flash
at http://www.plugcomputer.org/plugwiki/index.php/Enabling_UBIFS
except I made an empty image (no -r parameter for mkfs.ubifs).
After the ubiattach command it complained about a read-only fs
and some error messages from the kernel had appeared in the log:
