Well, I've had no problems (knock on wood) with getting DVD 4.01 installed and running from my HD. Only weirdness I've seen so far is the tendancy after a reboot for my wireless to sometimes show up as eth1 and sometimes as eth2. I didn't have this problem with the 4.0DVD, but that version still has the UB module, and I use several USB external drives. So many I had to do some mknod stuff today to deal with the USB drives now being /dev/sd rather than /dev/ub.

Process I followed was to boot the DVD, then use sudo to create a root passwd, then an su - to become root, and then run the "knoppix-installer" script. Prefer to run that as root to minimize any permissions issues.

FWIW,
Ewan
