Why is /tmp bind to meamo's /tmp?

Is there performance-difference when mounting a real partition or a image?

Maybe the soundhack should be checked and fixed whith a script when everytime debbie starts. Then it would be fixed if someone upgrade and breaks the pulsaudio.

You could install wajig to keep packages from upgrading.

wajig hold <package_name>
Then we could safely upgrade to squeeze.
