Hi BillK,
    your response motivated me to look at the latest shr-u image as I
was using one from mid November. Thought I'd best update it even thought
I'm sort of happy with what I've got at present. I do want to use wifi
for a demo so off we go. I grabbed the shr-u kernel from 29th of
November and the lite rootfs from 30th. Bit of a WTF moment there when I
failed to find any wifi antenna setting in "Settings/Connectivity" where
 I'm used to seeing it. Decided that I'd just enable the eth0 interface
with an ifup but get told that interface don't exist.

Maybe I leaped too far forward in time. Have you any recommendations as
to which version to use? I might go back a version and see how I get on.
Maybe I should be using the full root-fs but I only want the basics at

I did in the mean time discover coova-chilli for the first time. That
one slipped under my radar, like a good many other things. I'll go back
in time but if you've any advice on a good image let me know.
