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.

Thanks
