The issue is that while I can pause the boot process in initramfs and the filesystem appears all well and running if I run init off the filesystem some filesystem operations just fail at random leading to files seemingly missing intermittently and the live CD failing to boot. I realize this is tremendously useful information but that's all I can say about the issue which is why I did not bother to report it anywhere. I used whatever was packaged in Debian Squeeze.
