@ Gilles & others

Just made a liveusb from the Runtime 6.9.9 livecd.
kernel is 3.3.2.

Desktop includes Iceweasel, GParted & Synaptic.
wifi no better (or worse) than 6.7.1 in regard to Broadcom.
Lots of disk examination & recovery modules, use space
vacated by Office programs.

'Newness' is in the disk forensics and association with
Runtime in a commercial venture.
Knoppix 'newness' below my expectations for 7.0+ except for
kernel.

My liveusb never asked to set persistent store parameters.
That's a surprise. Will now do belated testcd on the cd.
