I just popped in to grab the suggested change by STraute for a fresh install on my work laptop and realised I did not reply to this thread to verify if I got this solved, at least for myself. Testing the default flash-knoppix2 using 3 flash drives (Sandisk Cruiser 8GB, Verbatim Tuff'n'Tiny 8GB and Centon PRO 16GB) all failed with my previously indicated message. Using the suggested change to the script in post #11 I am now able to use the experimental install with persistant reiserfs partition on all sticks. I really hope this change makes it into the next release (and that STraute gets all the credit ;,,; Happy Penguining!
