Hi, I have a persistent home directory at /home/knoppix and am booting the DVD from "knoppix bootfrom=/dev/hda2/knoppixdvd.iso". The knoppix hacks book said I could use the normal debian package management tools so I did a "sudo apt-get upgrade" and figured that the unionfs would orchestrate the updates against the live dvd using my persistent storage. I ran into trouble, which is why I'm posting.

The dvd is KNOPPIX_V5.1.1CD-2007-01-04-EN.iso, checksum-verified and has worked fine although I bootfrom a hard link to it called knoppixdvd.iso to make life easier.

The apt-get upgrade problem occurs after all the 700+ upgrades have been downloaded; then an ioctl problem happens, here's the information (where you see iinfo, remove one of the i's; I had to do this to avoid the spam filter):

There seems to be 315 MB of persistent storage available, so I don't understand what workaround I need to implement to finish the package upgrades.
